Charlie Hebdo hunt: Kouachi brothers killed in assault

French police have stormed two hostage sites in the Paris area, killing three hostage takers.

Two brothers suspected of the attack on Charlie Hebdo magazine on Wednesday were killed at a warehouse where they had held a hostage north of Paris.

In a second incident, in eastern Paris, anti-terrorist forces stormed a kosher supermarket where hostages were being held by a gunman with reported links to the brothers.

Gavin Hewitt reports from the scene in Dammartin-en-Goele.
