Nigeria: Gun battles in Nigeria oil region

Security forces and armed militiamen have clashed in Port Harcourt, in Nigeria's oil-rich Delta region. Residents say a number of people, including a woman bystander, died in the fighting, which took place in the city's Amadi-Ama district on Tuesday. Nigeria is Africa's biggest oil exporter, but the Niger Delta is one of the most underdeveloped regions of the country and is prone to violence.
