VIDEO: State of Emergency declared in France after 127 killed in Paris attacks

A state of emergency has been declared in France after a night of horror in the capital, where at least 127 people have been killed.

Two hundred others have been injured.

Shootings and explosions happened at six separate locations.

There were two suicide attacks and a bombing near the Stade de France stadium, shootings at restaurants and a massacre inside a popular music venue in what is the worst violence to hit France since the Second World War.

The French government have convened an emergency meeting on Saturday morning to formulate their response to the attack.

Eight attackers died, including seven in suicide bombings, but the city's prosecutor said it is possible there are still terrorists on the run.

Security has been stepped up and border control checks re-imposed after the attacks, which President Francois Hollande described as an “abomination”.

In horrific scenes officers stormed the Bataclan concert hall where hostages were being held but attackers, wearing suicide belts, blew themselves up, leaving 80 people feared dead.

Earlier reports indicated 100 people had been killed inside the venue.

During a visit to the concert hall in the early hours Mr Hollande, who has cancelled his trip to the G-20 meeting in Turkey, said the country will be “merciless” against those who have attacked them.

“We will lead the fight. We will be merciless,” he said.

The national football side was playing a friendly match against Germany at the Stade de France when two suicide attacks and a bombing took place nearby.

President Hollande had been at the stadium but was evacuated.

Gregory Goupil of the Alliance Police Nationale said there were at least three dead in the attacks near the stadium. He said the explosions went off simultaneously.

As many as 18 people died when the terrace of the Rue de Charonne was sprayed with gunfire, while around 14 people were killed when Le Carillon bar-cafe, and the nearby Cambodian restaurant Le Petit Cambodge, were also shot at, prosecutor Francois Molins said.

Two hundred people were injured in the string of attacks, French media reported.

Scenes of “carnage” were described by witnesses at the Bataclan, who said there was “blood everywhere”.

World leaders including Barack Obama and David Cameron have spoken of their shock and outrage at the violence.

The attacks come after the Charlie Hebdo atrocity, which took place in January and saw 12 people killed after gunmen stormed the offices of the satirical magazine.

They also come a day after Islamic State militant Mohammed Emwazi, known as Jihadi John, was targeted in a US air strike in Syria. It is not clear if there is any link.

President Obama told a press conference that the violence in Paris “was an attack on all of humanity”.

He said: “Those who think they can terrorise the people of France and the values they stand for are wrong.”

While Taoiseach Enda Kenny says his thoughts and those of all the Irish people are with the French citizens.

This is a shocking attack on humanity. Our thoughts and prayers are with the victims and families. We stand with France tonight.

The Vatican has also condemned the attack as “mad terrorist violence”.

Eyewitness Ben Grant said he was in a bar with his wife when the gunshots were fired and he had seen six or seven bodies on the ground.

He told the BBC: “I heard gunshots. People dropped to the ground. We put a table over our heads to protect us.

“We were held up in the bar because there was a pile of bodies in front of us.”

Television cameraman Charles Pitt said he was outside a cafe in the city’s 11th arrondissement where people were shot at around 9.10pm local time.

He told BBC News: “I had literally gone about 30 metres when, I thought it was a firecracker to start with, and then it went on and it got louder.

“It went on for a minute. Everybody dived for cover thinking it was gunfire. Then there was a pause for about 15 seconds and then it all started up again.

“Then it calmed down a bit and I walked back to the front of the cafe and there was a whole pile of bodies, probably about seven on the left-hand side and four that had been sitting on the tables outside on the right-hand side, and a lot of injured.

“I saw a woman who had obviously been shot in the leg.”

The Bataclan concert hall had been due to host a gig by US rock band Eagles Of Death Metal. All of the group have been accounted for and are safe, a US official said.
