Muslim guerrillas killed 10 civilians in the majority Catholic Philippines over Christmas, the military said Sunday, with some Christians in the affected areas now too scared to sleep in their homes.

Guerillas from the Bangsamoro Islamic Freedom Fighters (BIFF) captured nine farmers and shot them dead on December 24 in the southern island of Mindanao, said Colonel Ricky Bunayog, commander of the local battalion.

Some of the bodies were not found till two days later, he told AFP.
