Maidugiri, Nigeria: Police say four suicide bomb attacks Saturday killed at least 54 people and wounded 143 in the northeastern Nigerian city of Maiduguri that is the birthplace of the Boko Haram Islamic extremist group.
Police Commissioner Element Adoda said the blasts occurred over four hours in locations from a busy fish market to a crowded bus station.
Witnesses say a fifth explosion at a military checkpoint outside the city wounded three.
Boko Haram has attacked Maiduguri many times, with bombings and armed assaults since the insurgents were forced out of the city after a state of emergency was instituted in 2013.
