Three terrorists who seized hostages at separate locations and ignited fear across Paris were killed Friday along with three of their hostages as the gunmen clashed with thousands of French security forces. City officials scrambled to protect residents and tourists from further attacks, shutting down a famed Jewish neighborhood, putting schools under lock down and urging residents to stay indoors and remain vigilant. France has been high alert since the country’s worst terror attack in decades — the massacre Wednesday in Paris at the satirical newspaper Charlie Hebdo that left 12 people dead. Two al-Qaida-linked brothers suspected in the Charlie Hebdo killings came out of their hideaway with guns blazing Friday, a French police official said. Brothers Cherif Kouachi, 32, and Said Kouachi, 34, killed in a shootout and their hostage was freed, authorities said/AP. More here.
