A police representative said the gunman who took hostages at a kosher market died in a police raid, as did three hostages.
Explosions and gunshots were heard as police forces stormed a kosher grocery in Paris where a gunman was holding at least five people hostage.
A woman was seen leaving the building.
The assault came moments after a similar raid on the building where two brothers suspected in the Charlie Hebdo newspaper massacre were cornered.
The gunman at the market had threatened to kill those inside if the brothers were harmed.

PARIS -- A police official says the man who has taken at least five people hostage in a kosher market on the eastern edges of Paris Friday appears linked to the newsroom massacre earlier this week that left 12 people dead.
The official, who was not authorized to speak about the situation, said the man opened fire in the kosher market, near Paris' Porte de Vincennes, and declared "you know who I am."
Paris police released a photo of Amedy Coulibaly as a suspect in the killing Thursday of a policewoman, and the official named him as the man holed up in the market. He said the man is armed with an automatic rifle and some hostages have been gravely wounded.
He said a second suspect, a woman named Hayet Boumddiene, is the gunman's accomplice.
Helmeted SWAT squads converged on the standoff. The French president ordered the country's top security official to the scene, an official in the presidency told The Associated Press.
The two men suspected in Wednesday's attack on satirical newspaper Charlie Hebdo have been on the run since gunning down 12 people and remain cornered by police about 30 kilometres away.
France has been high alert for other attacks since the newspaper massacre.
