A military spokesman says three militants were killed and six captured during an unsuccessful attack on an oil facility in Nigeria's restive south. Lt.-Col. Rabe Abubakar says the gunmen died in a shootout with soldiers guarding a flow station operated by Italian oil company Agip in Bayelsa state. He says the oil facility was not damaged during in the attack early Friday but one soldier was badly injured. Attacks on oil industry infrastructure in the past two years have slashed oil output by almost a quarter in Nigeria, Africa's top crude producer. Militants say they want more petroleum funds to be spent developing their impoverished region.
