Police surround kosher Paris supermarket

A gunman has seized hostages at a kosher supermarket in Paris, while police in northern France have cornered the two Charlie Hebdo massacre suspects.

Armed police flooded the Porte de Vincennes area of the capital after the man reportedly opened fire and took up to five people hostage.

He is said to be the gunman who killed a policewoman in the city on Thursday.
