Six foreign oil workers who were kidnapped from an offshore oil field in the Niger Delta were released Tuesday after three days in captivity, officials said.
Gunmen in speedboats kidnapped the workers at dawn Friday from the Mystras, some 50 miles offshore. Another Nigerian worker was reported to have been wounded in the leg in the attack.
Locals for years have demanded a greater share of the wealth in Africa‘s largest crude producer, and the region remains desperately poor despite its great natural bounty.
A militant group, the Movement for the Emancipation of the Niger Delta, has claimed responsibility for Friday‘s attack.
The group, which threatened last month to resume attacks after one of its leaders was arrested in Angola, vowed to continue the violence.
