French police have stormed two hostage sites in Paris and north of the city.
Gunshots and explosions have been heard at a printworks warehouse in Dammartin-en-Goele, where two suspects in the Charlie Hebdo shootings were holding at least one hostage.
French media are reporting that the two suspects, brothers Cherif and Said Kouachi, have been killed.
Explosions and gunfire could also be heard at a kosher supermarket in eastern Paris, at Porte de Vincennes.
A gunman there was thought to be holding several hostages. Reports suggest he is linked to the Charlie Hebdo suspects.
Several hostages could be seen coming out from the Hypercacher supermarket.
The hostage at the print works warehouse has also been freed, AFP news agency said.
