Police have stormed a kosher supermarket in east Paris where several hostages were being held.
A hostage taker has reportedly been killed, these reports are unconfirmed.
Several hostages were seen being helped from the scene by police.
The police had named two suspects wanted in connection with the siege - Amedy Coulibaly and Hayat Boumeddiene.
Police did not specify whether both were at the scene.
Explosions were heard at around 4.15pm (GMT), shortly after similar scenes at the print works in Dammartin.
The gunman reportedly demanded the release of the two suspects at the siege in Dammartin, which was ongoing 25 miles away in north-east of Paris. That has now ended too.
The Hypercacher store is near Port de Vincennes in east Paris (see map below).
