Two female suicide bombers killed 22 people Wednesday at a mosque outside the northeastern Nigerian city of Maiduguri, a military spokesman said.
The attack, which also wounded 18 people, occurred during morning prayers in the village of Ummarari, four miles from the center the capital of Borno state and heartland of Boko Haram.
It was the first such assault in the northeast since early February, when two suicide bombers — also women — blew themselves up at a camp for internally displaced people in Dikwa, 50 miles from Maiduguri.
