Nigerian militants detonated two car bombs in southern Nigeria on Monday, seeking a greater share of oil revenues for their impoverished region.
Police official Bassie Inyang said no casualties were reported at either site.
At one, a compound belonging to Italian oil firm Agip, the force of the blast blew out windows of a medical facility and cracked compound walls.
Agip said in a statement that the car bomb was parked outside the compound wall and that no injuries were reported. Residents of the Shell compound hit by the other blast said several cars caught fire.
The Movement for the Emancipation of the Niger Delta (MEND) claimed responsibility in an e-mail to reporters, saying the bombs contained a mix of commercial and military-grade explosives and were triggered by mobile phone. A third attack was aborted as many civilians were nearby, it said.
