Unidentified drones have been spotted in the skies above Paris for a second night as authorities seek to determine whether the aircraft pose a security threat.
Police say at least five drones were seen at locations including the US Embassy, the Eiffel Tower and major thoroughfares in central Paris, as well as several of the city gateways.
A police source said the unmanned aircraft were reported by witnesses and security forces.
The unmanned aircraft have also been spotted near the Eiffel Tower
The source added: "Is it a game? Scouting for future operations? The investigation will show us."
On Tuesday, police said unmanned aircraft were spotted at the same locations, leading a security source to admit "we don't know" who is responsible.

The sightings are the latest in a series of unexplained drone flights in the French capital and elsewhere across the country.
Authorities were first alerted to mystery drone flights in October, when state-run power company EDF filed a complaint with police.
The company had detected tiny unmanned planes buzzing around the skies above seven atomic plants.
The sightings continued into November, and altogether some 20 flyovers took place near nuclear plants.
In January, a pilotless aircraft also flew over the presidential palace in Paris.
The mysterious flights come at a time when security measures have been stepped up in France in the wake of January's Charlie Hebdo attacks.
In France it is illegal to fly small civilian drones over sensitive areas like nuclear facilities.
Sensitive areas are protected by a no-fly zone that spans a 1.6-mile radius to a height of 1,000 metres.
The Speaker of the House of Commons has admitted he is partly responsible for the bad behaviour at Prime Minister's Questions.
In an exclusive interview with Sky News Stand Up Be Counted members, John Bercow MP said: "Do I accept some share of the responsibility for putting it right? I do."
He also gave his views on the "cash for access" scandal telling MPs Sir Malcolm Rifkind and Jack Straw they will "cop it" if it is proven they have broken the rules over claims they offered to trade their influence in return for money.
Four young people challenged the Speaker on how he runs Parliament as part of Sky News' campaign to give a voice to 18-24 year olds.
Chris Robertson, 24, from Lincoln, said he finds MPs' conduct at PMQs "horrible".
He said: "I'm a student union president and if I acted like that around my members I'd have been sacked by now.
"You've been speaking out for six years. Do you not think it should've been curtailed by now? Does it mean that you have failed in your job as leader of the house and Speaker?"

Mr Bercow replied: "Do I accept that the unreformed Prime Minister's Questions is a problem? I do. Do I accept some share of responsibility for putting it right? I do.
"Would I accept that it's all down to the Speaker? No I wouldn't. What I can't do, what no Speaker can do is make people behave decently if they don't want to behave decently.
"Members have got to take responsibility for their own conduct in the chamber.
"And I think my point would be to ask members who shout regularly - would you be content for your constituents to see and hear you if you if you were caught on camera?

"And if the answer is they would be content, there is something wrong, and if the answer is that they wouldn't be content then they should change the way they behave."
The Stand Up Be Counted contributors were given rare access to the Speaker in the Palace of Westminster as part of attempts to engage young people in politics.
Less than half of 18-24 year olds voted at the last election, with young women the least likely to vote by some margin.
Eighteen-year-old Ellie James, from Grimsby, challenged the Speaker about the lack of female MPs.
Video:What They Thought Of Mr Speaker
He criticised the main parties for not doing enough, saying: "I think the parties talked the talk and have made some progress but I don't think they anything like as effectively walked the walk, so I would look to the parties to do more there."
He also revealed that he seeks to make sure women are called to speak in the Chamber, adding: "I don't like calling lots of men in a row. I always have in mind what female colleagues I have called today. And if I may say so, and this isn't meant in a patronising sense at all, but the simple fact is women on the whole are better behaved in parliament than the men.
"They're just as tough, they're just as capable, they can withstand parliamentary life just as much as men can. They don't sit there like shrinking violets but on the whole they're better behaved and don't shout as much as men do."
Jaspreet Kaur, 18, from Birmingham, told Mr Bercow that when she looks at Parliament, all she sees is "grandeur and confusion" and that it can be difficult to understand.
The father of missing chef Claudia Lawrence has said it is "dreadful" that people may have been lying to police investigating her disappearance almost six years ago.
Officers have been carrying out a detailed search of an alleyway at the rear of Miss Lawrence's terraced home in York, and Detective Superintendent Dai Malyn, who is leading the inquiry, has said he was sure people have lied to his officers.
Peter Lawrence commented: "I heard that and it's obviously absolutely dreadful that anyone would do that.
Peter Lawrence: 'People should tell the truth'
"We know that people lie to the police but in a case like this that involves Claudia's disappearance and everyone can see what it's done to the family... come on."
Miss Lawrence was 35 when she went missing and her family are preparing to mark what would have been her 41st birthday on Friday.
Video:Claudia Lawrence Alleyway Search
She was last seen on Wednesday 18 March 2009 and was reported missing by her father two days later after she failed to turn up for work at York University.
North Yorkshire Police began reviewing the case in 2013 and have since carried out a number of searches, including a detailed re-examination of Miss Lawrence's house in the Heworth area of the city.
On Wednesday the alley behind the house was cordoned off as specialist officers conducted a fingertip search. An officer with a dog was also involved in the operation.
Mr Malyn, who is head of the force's major crime unit, said: "We still don't know if Claudia left for work on the morning of Thursday March 19 or whether something happened overnight within her house.

"If the latter is the case, the person or persons responsible, in my view, would have used the rear alleyway as the front door leads on to a busy main road. This is why this specific piece of information needs to be fully investigated."
Officers have also been conducting house-to-house inquiries in the area and speaking to people who have since moved away, as well as checking all possible CCTV image have been obtained.
Last year a 60-year-old man was arrested on suspicion of killing Miss Lawrence but was later released without charge.
A 47-year-old man remains on bail on suspicion of perverting the course of justice.
Iran has staged a series of military drills, including a simulated attack on a US aircraft carrier, on one of the most strategic stretches of water in the Gulf.
The Islamic Revolutionary Guard launched the display of naval and air exercises near the Strait of Hormuz, through which one fifth of the world's oil supply passes.
Video on Iranian TV showed the deployment of fast boats and missiles against a replica of an American carrier - something not seen before in military drills.
Other exercises included the shooting down of a drone and planting undersea mines.
The unit's navy chief Admiral Ali Fadavi said: "American aircraft carriers are very big ammunition depots," explaining that a direct hit could create huge secondary explosions.
Chief Commander General Mohammed Ali Jafari explained that the exercise - dubbed Great Prophet 9 - sent a "message" to "extraterritorial enemies", in reference to the United States.
The Strait of Hormuz is one of the most strategic stretches of water
The television footage also panned across a banner showing the words: "If the Americans are ready to be buried at the bottom of the waters of the Persian Gulf, so be it."
But a spokesman for the US Navy's 5th Fleet in Bahrain downplayed the threat, saying he was "confident of our naval forces' ability to defend themselves".
Commander Kevin Stephens added: "It seems they've attempted to destroy the equivalent of a Hollywood movie set."
The US is currently in negotiations with Iran over a potential nuclear deal, alongside Britain, France, China, Russia and Germany.
Tehran has always denied Western claims that it intends to develop atomic bombs.
Talks are due to resume in Geneva next week after a meeting between Iranian foreign minister Mohammad Javad Sarif and the US Secretary of State John Kerry on Monday.
A framework agreement between the two sides is hoped for before the end of March with all eyes on a final deal by 30 June.
Ed Miliband has attempted to put pressure on David Cameron to ban MPs from second jobs, offering a deal on paid trade union officials.
The Labour leader called on the Prime Minister to "restore the reputation of the House" following the cash-for-access revelations about Sir Malcolm Rifkind and Jack Straw during angry exchanges at Prime Minister's Questions.
Mr Miliband has forced a vote on his proposals banning MPs holding outside directorships and consultancies in the House of Commons later today.
Mr Cameron defended the right of MPs to do second jobs in addition to their £67,000-a-year MP role saying it was good to have politicians with other interests.
He criticised Mr Miliband's proposals saying they would allow paid trade union officials to be MPs but not those running a family business.
Video:'We Don't Want A Sixth Form Brawl'
However, Mr Miliband offered to make a deal to include paid trade union officials, although there are currently no MPs in this situation.
The Labour leader said: "But what is in the motion today is something very specific which is being a paid director or a paid consultant. I have said from this Despatch Box we will also ban people being a paid trade union official, the offer you made to me, I repeat the offer to you.
"Let's get it done, let's agree this to restore the reputation of this House.
"Yes or no?"
Video:The Best (Or Worst) Of PMQs
Mr Cameron pointed out that it was possible to have two jobs but added he spent more time on his duties as PM than on work linked to his seat in Witney, Oxfordshire.
He said: "We have practising doctors in this House, we have practising dentists, we have people who take part serving our country in Afghanistan or Iraq and we do have people who run family businesses or have other interests.
"What you want is a Parliament where people can come and share their experience and make some points instead of just having a whole lot of trade union-sponsored ciphers."
Mr Miliband highlighted comments made by Mr Cameron in 2009 when he said in an interview: "Double-jobbing MPs won't get a look-in when I'm in charge."
Video:Speaker Stands Up To Be Counted
The row over second jobs comes on a day when figures from the Office for National Statistics show an increasing number of people were having to juggle zero-hours contracts to make ends meet.
Speaker John Bercow had to call for calm a number of times including to allow the Labour MP Rushanara Ali to ask a question about the three schoolgirls who fled the UK for Syria.
Mr Bercow told Sky News earlier that he took some of the blame for the bad behaviour at Prime Minister's Questions.
There has been increasing criticism of the format of "Punch and Judy" politics and calls for the sessions to be reformed.
The boss of HSBC has apologised in person to MPs over the past behaviour of his bank and thousands of secret Swiss bank accounts it held for clients.
Stuart Gulliver told MPs on the Treasury Select Committee that revelations about thousands of secret accounts held in Switzerland has caused "damage to trust and confidence".
He said: "I am apologising as CEO. I am responsible for cleaning it up."
Committee chair Andrew Tyrie MP asked Mr Gulliver why he found it necessary to shield his income through a shelf company located in Panama, while he was actually domiciled in Hong Kong.
Mr Gulliver stressed it was not for "tax purposes", instead saying it was because he did not trust other members of staff at the bank.
"It was purely about privacy. Privacy from colleagues in Hong Kong and privacy from colleagues in Switzerland," Mr Gulliver, whose has worked for the bank for 35 years, said.
"That was because my pay was not a matter for public record."
He said the HSBC computer system at the time allowed staff to snoop on each other to find out how much they were paid.
Mr Gulliver admitted he was one of the best remunerated members of staff in Hong Kong.
He said: "The computer system showed everyone's pay and I was amongst the highest paid and I wished to preserve my privacy."
Protesters gathered outside Parliament as Mr Gulliver spoke to MPs
Protesters outside the House of Commons chanted anti-HSBC slogans, as public anger continues to rise over the secret accounts promoted by the bank's private arm in Geneva.
Swiss investigators raided the offices of the bank last week after reports said it turned a blind eye to handling funds for arms dealers and traders in conflict diamonds.

That announcement came just over a week after HSBC Switzerland found itself at the centre of a global scandal following the publication of secret documents.
The cache of files, made public in a French newspaper, claimed HSBC's Swiss private banking arm helped clients in more than 200 countries evade taxes on accounts containing £77bn ($119bn).
The files, which include the details of 30,000 accounts and the names of celebrities, were originally stolen by former HSBC IT worker Herve Falciani in 2007.

A number of regulators have launched investigations into the HSBC tax scandal.
In 2012 the bank agreed to pay fines and settlements of £1.2bn over an unconnected matter.
That followed a US investigation of Europe's largest bank which focused on the transfer of funds on behalf of nations such as Iran and the movement of $7bn (£4.5bn) in cash into the US financial system, suspected to have belonged to Mexican drug cartels.

At the time Mr Gulliver apologised for the actions of his bank, which dated back to 2007 and 2008.
He said: "We have said we are profoundly sorry for them, and we do so again.
"The HSBC of today is a fundamentally different organisation from the one that made those mistakes."
The driver of a bin lorry that crashed in Glasgow, killing six people, will not face any charges, Sky News has learned.
A decision has also been made not to charge Glasgow City Council, which owned the vehicle involved in the tragedy, although a Fatal Accident Inquiry will be held.
Scotland's prosecuting body, the Crown Office, has been studying a police report into the tragedy which occurred on 22 December.
The incident saw the vehicle career out of control down one of Glasgow's busiest streets and collide with pedestrians.
Six people died in the tragedy on Glasgow's Queen Street
Six people lost their lives and a number of others were injured. Those who died included three members of the same family, 18 year-old Erin McQuade and her grandparents Jack and Lorraine Sweeney.
Stephanie Tait, a 29-year-old primary school teacher, from Riddrie, Glasgow, Gillian Ewing, 52, from Edinburgh, and Jacqueline Morton, 51, from Glasgow, were also killed.

In Scotland, a Fatal Accident Inquiry (FAI) is held when there is deemed to be sufficient public interest in establishing the facts surrounding a death.
It is held before a Sheriff who, ultimately, issues a determination. Witnesses are compelled to attend.
It is possible for charges to be laid on the basis of evidence given during an FAI.
Inquiries will look at all the circumstances surrounding the tragedy, which happened when the bin lorry driver, 58-year-old Harry Clarke, collapsed at the steering wheel.
Video:Faint Light In The Darkness
The vehicle headed erratically along Glasgow's Queen Street at a speed of just over 20mph.
Two crew members in the rear of the driver's cab made desperate attempts to rouse him but were hampered by a safety rail separating the front and back of the cab.
Following the crash, Mr Clarke tested negative for drink-driving.
Police have released photographs of seven men they wish to identify following alleged racist chanting at London's St Pancras International station last week.
British Transport Police (BTP) say the images were captured at 8pm last Wednesday, the day after Chelsea's Champions league match in Paris.
Sky News understands two of the men who feature in the images have identified themselves to police.
Officers believe the group had returned to London following the match against Paris Saint-Germain (PSG).
A member of the public reported being "disgusted" by the men's chanting and reported their behaviour to police.
Video:'We Don't Want Them At Our Club'
Detective Sergeant Steven Graysmark said: "I want anyone who knows the men in the photographs to come forward.
"I believe the seven, thought to be Chelsea fans, can help us with the investigation.
"Do you know any of the men in the images? If so, please contact BTP."
A similar incident was reported on the Paris Metro shortly before the Chelsea match on 17 February.
On Friday the club suspended five people after video emerged of a commuter being pushed on the Paris Metro.
The commuter, Sylla Souleymane, appeared to be stopped from getting on an underground train by fans.
The fans were also heard in the video chanting "we're racist and that's the way we like it".
Video:PM: Chelsea Incident 'Disturbing'
The club said the fans had been suspended from its Stamford Bridge ground and that they would be banned for life if there was "sufficient evidence of their involvement".
Mr Souleymane said last week that he thinks those who abused him in Paris should be jailed for their actions.
The 33-year-old told Le Parisien newspaper: "These people, these English fans, must be found, punished and must be locked up.
"What happened should not go unpunished."
He said he thought Chelsea and PSG should face sanctions because it was "also their fault".

More than 100 people have been killed in avalanches triggered by two days of heavy snowfall in Afghanistan.
Rescuers have been battling treacherous conditions in their attempts to reach those still buried underneath the snow.
Most of the victims were in the northern Panjshir province, where snow has blocked main roads leading up to the villages affected, and dozens remain unaccounted for.
Provincial governor Abdul Rahman Kabiri said a team of 300 emergency workers had been sent to help, but a lack of adequate tools was hampering the operation. "We don't have the equipment we need and people are using shovels and their bare hands to reach the trapped people," he said.
At least 100 homes have also been destroyed in what has been described as the worst avalanches the country has seen in 30 years.
The blizzard has left parts of Kabul without electricity after hitting power cables along the Salang Pass, which connects the capital to the country's north.
The current conditions are expected to last for another two days, prompting fears of an imminent humanitarian emergency.
This week's storm interrupted an otherwise mild and dry winter, but natural disasters are common in Afghanistan's mountainous north.
Last May, up to 2,700 people were killed after a mountain collapsed in Badakhstan province. Another landslide left 75 people dead in Baghlan province in 2012. The vast majority of bodies were never recovered, and the site was eventually turned into a memorial site.
Despite an influx of international aid to Afghanistan following the collapse of the Taliban, it remains one of the poorest countries in the world and rescue operations are often beset by a lack of funding and infrastructure.
