French security forces are mobilizing in their search for what the the prime minister calls a "probable" accomplice to three days of bloodshed and terror around the capital.

Manuel Valls said the search is urgent because "the threat is still present" after the attacks that left 17 people dead — journalists at the satirical newspaper Charlie Hebdo, hostages at a kosher market and three police officers. All three attackers died Friday in nearly simultaneous raids by security forces.

Video emerged on Sunday of one of the attackers explaining how the attacks would unfold and police want to find the person who shot and posted the video.

Valls told BFM television on Monday that France is at war against "terrorism, against jihadism, against radical Islam."
