French police hunt for terror accomplices

French police are searching for accomplices involved in the deadly attacks around Paris over the past three days, including the companion of a suspect who took several people hostage at a kosher supermarket in the east of the city.

Amedy Coulibaly was killed during a police siege on the supermarket, in which four hostages died.

His partner, Hayat Boumeddiene, was said to be with Coulibaly when a policewoman was killed and is described as "armed and dangerous".

The couple were married in a religious ceremony but were not wed under French law which requires a civil ceremony.

Coulibaly also told BFM channel he was a member of the Islamic State jihadist group, which had called for attacks in France and other countries participating in US-led airstrikes against the militants in Iraq and Syria.

He shot two people as soon as he entered the kosher store in Porte de Vincennes neighbourhood and had "one or more bags" of explosives with him but did not detonate them, a security source said.

He had tried to boobytrap the entrance to the shop where he was besieged by police "but had not hooked up the explosives", the source added.

Two gunmen who carried out Wednesday's deadly attack on Charlie Hebdo magazine were killed by police on Friday.

President Francois Hollande praised the police but also warned of further threats.
