Explosions and gunshots have rung out and smoke is rising outside a building in Dammartin-en-Goele where two brothers suspected in the Paris newspaper massacre are holed up with a hostage.

Gunfire and explosions have been heard in Dammartin-en-Goele where two brothers, believed to be responsible for the Charlie Hebdo killings in Paris, are holding a hostage.

The gunman holding at least five hostages in a kosher market in eastern Paris has threatened to kill them if police launch an assault on the cornered brothers suspected in the newspaper massacre earlier this week, a police official said.

A shooting and hostage-taking attack is under way at a kosher market on the eastern edge of Paris, France’s anti-terrorism prosecutor said.

France has been rocked by a fresh hostage situation after the hunt for the Charlie Hebdo gunmen developed into a siege.

A third shooting has reportedly broken out in eastern Paris. It is reported an armed man has taken a hostage in a kosher grocery in Porte de Vincennes in eastern Paris.
