LAGOS - A private security official says gunmen have attacked two oil facilities operated by the Royal Dutch Shell in Nigeria's restive south.
The official says that a local militant leader claimed responsibility for the attack early yesterday in a letter and threatened further violence. The security official spoke on condition of anonymity due to company prohibitions on dealings with the media.
Military and Shell officials were not immediately available for comment.
Nigeria is Africa's largest oil producer but three years of militant attacks on the industry have kept the country's daily crude production at about 25 percent under its estimated capacity of 2,5 million barrels a day. - Sapa-AP
