The two brothers wanted for the shooting of 12 people at the offices of satirical weekly Charlie Hebdo were killed in a raid on Friday by security forces on the print works where they were holed up with a hostage, a government source said.
Separately, Le Monde newspaper quoted a police official as saying that the hostage-taker at a separate stand-off at a kosher supermarket in eastern Paris had also been killed. That hostage-taker is believed to have links to the same Islamist group as the two brothers.
French television images showed some people running out of the supermarket in eastern Paris. The exact fate of all the hostages there and at the one at the print works was not immediately clear.
