'10 horrific minutes': Eyewitness talks about bloodbath at concert
An eyewitness has described "10 horrific minutes" when gunmen stormed the Bataclan concert hall.
Officers entered the venue where hostages were being held but attackers, wearing suicide belts, blew themselves up, leaving 80 people feared dead - with earlier reports indicating 100 had been killed.
Julien Pearce was at the theatre listening to American rock band Eagles Of Death Metal before the horror unfolded.
"I seen two terrorists from my point of view with AK47 Kalashnikovs entering the concert room and firing randomly to the crowd. People yelled, screamed," he said in an interview with CNN which was broadcast on BBC Radio 5 Live.
He added: "It lasted for 10 minutes, 10 minutes, 10 horrific minutes where everybody was on the floor covering their head, and we heard so many gunshots and the terrorists were very calm, very determined, and they reloaded three or four times their weapons.
"And they didn't shout anything, they didn't say anything."
He said: "They were wearing black clothes and they were shooting at people on the floor."
Mr Pearce said that people tried to find an exit to escape and when he got out on the street he saw 20 to 25 people lying on the ground.
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.
Marc Coupris, 57, said he thought his "final hour" had come when the gunmen started firing into the crowd.
"It looked like a battlefield, there was blood everywhere, there were bodies everywhere. I was at the far side of the hall when shooting began," he told the Guardian.
"Everyone scrabbled to the ground. We just stayed still like that. At first we kept quiet. I don't know how long we stayed like that, it seemed like an eternity.
"I saw my final hour unfurl before me, I thought this was the end. I thought I'm finished, I'm finished. I was terrified."
