LAGOS, Nigeria (AP) - A military spokesman says soldiers have attacked three militant camps in Nigeria's oil-rich southern delta.

Lt. Col. Timothy Antigha says a military forces began their attack Wednesday afternoon in Delta state, an oil-producing state in Nigeria's southern Niger Delta.

Antigha says soldiers have recovered anti-aircraft guns, rocket-propelled grenades, automatic weapons and dynamite in the raid. Antigha declined to say whether there had been casualties.

Militants in the Niger Delta have attacked pipelines, kidnapped petroleum company employees and fought government troops since 2006.
