Paris gunmen 'no older than 25' - survivor

A survivor of the shooting at a Paris concert hall gives his account of what happpened, after a series of attacks in the French capital kills more than 120 people.

Jerome Bartelemy was one of many inside the packed Bataclan music hall, when the shooting started.

"We were by the bar, so we heard firecrackers, or what we thought were firecrackers. We turned around and then I saw two young men, no older than 25, with Kalashnikovs.

"They told us to lie down, there was one who kept gesturing for us to get down. Everyone in the whole room lay down. I was completely under other people, they kept shooting, but they would stop from time to time."

"The one I saw, he was wearing a black tracksuit with white stripes, he was no older than 25. The guy had brown hair, he was pretty calm. That's what really surprised me.

"At a certain point, I turned around and we were wondering if they were real bullets or not, and I saw him shoot someone and then I understood."

Officials say four gunmen shot dead more than 87 people, before anti-terrorist commandos launched an assault on the building and rescued survivors.

Around 40 more people have been killed in five other attacks in the Paris region.

Parisians have been warned to stay home and leave the streets, and to give shelter to anyone caught outside.

French President Francois Hollande has called it an unprecedented terrorist attack and declared a nationwide state of emergency.
