The prime suspect in the attack on satirical magazine Charlie Hebdo was an active member of a loose network of French militants, active for over two decades, that stretched from Syria to the UK.
Cherif Kouachi, 32, had been imprisoned for 18 months for his role in a network sending volunteers to fight alongside al-Qaida militants in Iraq between 2003 and 2005 and had been investigated for his involvement in a plan to break a veteran extremist out of prison in 2010.
