Charlie Hebdo attack: Suspected gunman 'nice and helpful'
Police in France are hunting for two brothers of Algerian descent following Wednesday's shooting at the offices of the satirical magazine Charlie Hebdo, which left 12 people dead.
The attack has sparked fears among French Muslims, some of whom fear a backlash following the murders.
Fergal Keane visited the estate where one of the suspects, Cherif Kouachi, lived. His neighbour described him as a nice, helpful man.
