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.
