An official in southern Nigeria says two recently kidnapped Philippine oil workers have been freed.
The government spokesman, Emmanuel Okah, in Rivers State said the two workers abducted Tuesday from the troubled Niger Delta region were released Sunday. He did not say if negotiators paid a ransom, which is frequently demanded by kidnappers in the oil-rich region.
The two workers are employees of the Norway-based oil services company Petroleum Geo-Services. They were abducted by armed men from an oil rig near the city of Port Harcourt.
Militants targeting Nigeria's oil industry have kidnapped some 31 foreign workers since January. All have been released unharmed.
The militants are demanding a greater share of the region's oil wealth. Some information for this report was provided by AFP, AP and Reuters.
