Muslim sect suspected of killing 5 in Nigeria

Police say members of a radical Muslim sect shot and killed three prison guards, a police officer and a woman in recent attacks in Nigeria's troubled northeast.

Borno state Assistant Police Commissioner Usman Baba said Wednesday that the attacks took place over two days in the city of Maiduguri. Baba said four men hiding Kalashnikov rifles under their traditional robes killed the people in attacks across the city.

Baba said police suspect the attackers belong to an Islamic sect known as Boko Haram.

Boko Haram was thought to be broken up in July 2009 after its leader was arrested and died in police custody.

The group, whose name means "Western education is sacrilege" in the local Hausa language, has previously attacked churches and engineered a massive prison break.
