Dutch oil giant Shell says it has resumed normal production at a Nigerian oilfield that was shut down last month after militants took four oil workers hostage.
Shell officials say the offshore EA oilfield is back to producing about 115,000 barrels of crude per day.
The hostages were captured from a boat working the field on January 11. They were freed Monday after spending 19 days in captivity.
Militants seeking greater local control over oil wealth in southern Nigeria have threatened more attacks on oil workers and facilities in the region.
A string of recent attacks, some of which were deadly, has contributed to a rise in world oil prices.Some information for this report was provided by AFP and Reuters.
