An oil company says gunmen in Nigeria's troubled Niger Delta region have attacked an offshore rig, kidnapping five people and wounding two others.
The company that runs the rig, Afren, has not confirmed the nationalities of those kidnapped. But security sources say they are two Americans, two French and one Canadian.
Gunmen in speedboats late Sunday attacked the oil rig, located about 12 kilometers off the coast of Nigeria's Akwa Ibom state.
The company said the two wounded employees have leg injuries and were flown by helicopter to a clinic on shore.
