Militants battle Nigerian forces in oil region

Militants fought a rare ground battle with Nigerian armed forces in the country's southern oil region Saturday and threatened to launch reprisals on the oil infrastructure in Africa's biggest crude producer. The Movement for the Emancipation of the Niger Delta told The Associated Press in a statement that the Nigerian army and navy raided their positions on Rivers State, pouring in ground troops from landing craft and bombing their fighters from jets and helicopters. They said seven militants were killed. Lt. Col. Sagir Musa of the military task force charged with calming the restive oil region confirmed an armed engagement Saturday, saying it was a response to an ambush by militants. Musa, however, said aircraft provided reconnaissance only. He had no details on casualties.
