"There was blood everywhere" said a TV reporter who was one of the first people to enter the Charlie Hebdo office after the attack which killed 12 people and left several others injured.

Wandrille Lanos works across the hall from the satirical magazine's office in central Paris.

He said "honestly we'd never assumed that they would carry out such a massive, violent and brutal attack against Charlie Hebdo".

Four of the magazine's well-known cartoonists, including its editor, were among those killed, as well as two police officers.
