Four people including a gunman were killed inside a kosher supermarket in Paris after a man armed with an AK-47 took the busy store hostage, the third deadly attack in a 52-hour string of terror that has seized the city.

French authorities stormed two hostage sites Friday afternoon, killing the suspected gunman in the supermarket and two brothers in a printing shop in northern Paris where the two men, suspected of carrying out a massacre Wednesday in Paris, were holed up with one hostage, who was safely freed.
