The two hostage situations gripping Paris ended with multiple hostages successfully freed within minutes of one another after intense bursts of gunfire and explosions.
At the Dammartin siege, northeast of Paris, where the Kouachi brothers were holding a hostage in a printers' warehouse, yen seconds of gunfire were followed by two set of explosions and heavy smoke.
Police confirmed that Said and Cherif Kouachi, the chief suspects in Wednesday's deadly attack on the Charlie Hebdo offices in Paris, had been killed.
The hostage, believed to have been the manager of the printing works, was freed and safe, according to AFP.
The Koachi brothers were killed after they ran out of the industrial zone, shooting at police with Kalashnikovs as they went, according to iTele.
Twenty minutes after that assault, at around 5.10pm, at least three loud explosions were heard from the Hypercacher supermarket, followed by what sounded like bursts of rapid gunfire.
Police were reported to have stormed the building, at Porte de Vincennes.
At 5.23 what sounded like another gunshot was heard as the operation to bring the Vincennes siege to an end continued.
Armed police had been surrounding the building since around 1pm after receiving initial reports that gunmen had taken hostages inside.
Coulibaly was killed in the assault, judicial police told Europe1.
"Several" hostages have been reported freed, with at least one confirmed sighting of a woman leaving the store alive.
