“Royal Dutch Shell said on Sunday it had shut down three pumping stations in Nigeria’s Niger Delta after a key crude oil pipeline was sabotaged.
Although there has been no claim of responsibility, the attack occurred a day after Nigeria’s main militant group MEND called off a three-month-old ceasefire and threatened to unleash ‘an all-out assault’ on Africa’s biggest oil and gas industry.”
