Some suspected militants have bombed a state-run oil pipeline near the southern Nigerian oil hub of Warri in the latest blow to the industry, a security source and community leader said Wednesday.

The Trans Forcados export line was attacked late Tuesday, they said, just hours after President Muhammadu Buhari met with representatives of militant groups in the oil-rich Niger delta to discuss how to end the unrest plaguing the region.

No group has yet claimed responsibility for Tuesday’s attack.

“The attack was carried out with the aid of dynamite and it is coming less than 48 hours after the resumption of operations at the flow station,” a security official, who declined to be named, told AFP.
