The Nigerian Army has destroyed 74 illegal oil refineries and several militant camps in the oil-rich Niger Delta, an army spokesman said on Friday.
The army carried out raids based on a tip-off in Rivers and Bayelsa States on Wednesday, where oil pipelines and refineries are regularly attacked by militants, spokesman Sani Usman said in a statement.
No arrests were made since the militants managed to escape, but some weapons and ammunition were recovered.
