The Niger Delta Avengers have announced yet another big blow to the Nigerian economy by way of the blowing up of yet another major crude oil pipeline.

A tweet this morning on the militant group’s official handle said: “3:am of Friday @NDAvengers blow up the Obi Obi Brass Trunk line belonging to Agip ENI. It is Agip’s Major Crude oil Line in Bayelsa State.”

The attack came just hours after Niger Delta militants last night blew up another pipeline belonging to the Nigerian Petroleum Development Company (NPDC), a subsidiary of the Nigerian National Petroleum Corporation (NNPC). The pipeline is located at Chanomi Creeks in Warri South West Local Government Area of Delta State.

The militants stormed the facility in two fast boats at about 7:45 p.m. and used dynamite to blow up the crude oil pipeline at Kurutie which supplies crude oil to Warri and Kaduna refineries.

No group has claimed responsibility for the attack.

The attacks have continued despite the two weeks unilateral ceasefire declared early this week by the Nigerian Government in a bid to get the militants to submit to dialogue.
