Military: Troops blow up 3 explosive-laden vehicles outside northeast Nigerian oil depot

Multiple explosions blasted near an oil depot outside the northeast Nigerian city of Maiduguri and the military says soldiers blew up three vehicles laden with explosives.

A fourth vehicle exploded, apparently by a suicide bomber.

The military says four suicide bombers died and five soldiers were wounded in Tuesday's blasts. It's the latest in a string of deadly attacks in an Islamic uprising that has killed nearly 1,500 people in northeast Nigeria this year.

A security official said three blasts damaged the perimeter fence of a radio station opposite a government oil depot and fuel station outside Maiduguri, the capital of Borno state that is the birthplace of the Boko Haram terrorist network.

Two weeks ago extremists attacked the main military barracks in Maiduguri and freed hundreds of detainees.
