An explosion ripped through a Catholic church during Christmas Mass near Nigeria's capital Sunday, killing at least 25 people, officials said. A radical Muslim sect, Boko Haram, claimed the attack and another bombing near a church in the restive city of Jos, as explosions also struck the nation's northeast. Boko Haram's insurgency started with robed men on motorcycles killing their enemies one at a time across Nigeria's remote and dusty northeast. Now the radical Muslim sect's attacks have morphed into a nationwide sectarian fight. (AP Photo/Dele Jones, File)
