(SomaliNet) Nigeria's oil saga is continuing. This time, Agip oil flow station in Nigeria's Bayelsa state has been attacked and at least two foreign oil workers have been kidnapped. "There was an attack on an Agip flow station at Brass about 5am. They came in about seven boats. Two or three expatriates were kidnapped," Hafiz Ringim, Bayelsea state police commissioner, told Reuters. However, Agip's spokesman in Nigeria's city of Lagos denied having any information on this attack by press time. Kidnapping of foreign oil workers is common among Nigerians. However, in most cases, they are released unharmed after payment of a ransom to the kidnappers. Nigeria is the world's eighth biggest oil producer, though its natives remain very poor. This has been cited as one of the causes of the frequent kidnappings.
