This is the shocking moment terrified concert-goers dragged their dying friends along a street and desperately clung to window ledges while fleeing the Paris massacre which has left at least 127 people dead and France in a nationwide state of emergency.

They were among dozens fleeing through a back exit of the Bataclan theatre where Islamic State gunmen mercilessly slaughtered up to 100 fans before blowing themselves up in a series of co-ordinated attacks across the French capital.

France was placed in lockdown after at least eight militants, all wearing suicide vests, brought unprecedented violence to the streets of the French capital in the bloodiest attack in Europe since the Madrid train bombings in 2004.

Francois Hollande accused ISIS of orchestrating the worst attacks in France for more than 70 years, declaring it an 'act of war' and vowing to 'mercilessly' strike back.

In a televised address, the French President said the attacks were 'committed by a terrorist army, the Islamic State group, a jihadist army, against France, against the values that we defend everywhere in the world, against what we are: a free country that means something to the whole planet'.

Police are also hunting accomplices amid fears of further attacks, with the arrest of a 51-year-old man in Germany last week after firearms were

discovered in his car now being linked to the atrocities, according to media reports
