Masked gunmen stormed the Paris office of satirical French newspaper Charlie Hebdo early Wednesday, killing at least 11 people before escaping in cars, police say. French President Francois Hollande said it was "undoubtedly a terrorist attack," adding that several other attacks have been thwarted "in recent weeks." Ten other people were wounded in the attack on the weekly paper, five of them critically. France raised its national security threat level to its highest position.
(Update: Police have raised the death toll to 12, including two police officers.)
Charlie Hebdo has been attacked before, notably after printing caricatures of the Prophet Muhammad, including being fire-bombed 2011.
