A militant group in Nigeria says it has temporarily withdrawn a threat of major attacks on oil facilities in the nation's oil-rich Niger Delta region.

Two leaders from the militant Niger Delta People's Volunteer Force, Alali Horsfall and Dakuro Princewill announced the suspension Saturday.

The militants had threatened to threatened to carry out the attacks unless Nigeria's government released their leader, Moujahid Dokubo-Asari, by Saturday.

Mr. Dokubo-Asari was arrested Tuesday. Police said he will be charged with treason for comments he made supporting the breakup of Nigeria.

A few days after his arrest, ethnic Ijaw militants seized an oil plant operated by Chevron, forcing the U.S.-based oil company to cease operations there. Chevron shut down a second oil plant in Nigeria Friday.
