Bomb explodes near north Nigeria Islamic school

LAGOS, Nigeria (AP) — Gunmen detonated a bomb Sunday near an Islamic boarding school in northern Nigeria and later exchanged gunfire with security forces, causing unknown casualties in the region’s latest round of violence, officials said.

Sunday’s attack hit Zaria, a city in the northern reaches of Kaduna state that is the nerve center of Shiite Muslims in a country where Muslims are predominantly Sunni. The blast struck the Gaskiya neighborhood in the city, causing some injuries, said Yushau Shuaib, a spokesman for Nigeria’s National Emergency Management Agency.
