Police killed three terror suspects today in twin standoffs that left four hostages dead and a nation on edge.

Some hostages were seen fleeing the site of one standoff, a Paris kosher market, and officials later said that four hostages were killed there.

And at a concurrent standoff at a printing company in the town of Dammartin-en-Goele, 20 miles northeast of Paris, police killed the Charlie Hebdo attack suspects as the brothers -- one of them previously wounded -- came out of the building with guns blazing, French officials said.

After the siege was over, police found automatic weapons, Molotov cocktails and a rocket propelled grenade, primed and ready to launch, the Paris prosecutor said.

The dramatic developments came after sustained gunfire and small explosions erupted at both hostage situations in France, two days after a massacre at the Paris offices of the satirical newspaper Charlie Hebdo.

There were at least four explosions and a barrage of gunfire at the market in the Porte de Vincennes area of Paris and then police were seen going in. People then were seen coming out of the market, and ambulances and firetrucks drove towards the market, loaded people in and drove away. After that siege was over, police found explosives around the shop tied to a detonator, the Paris prosecutor said.
