Nigerian militants claim attack on oil facility

LAGOS, Nigeria (CNN) - Nigeria's main militant group said Sunday it had attacked another oil facility, "leaving total destruction in its wake."

The Movement for the Emancipation of the Niger Delta (MEND) issued a statement saying it had "lashed out at the Shell Well Head 20, located at Cawthorn Channel 1" at 3 a.m.

Royal Dutch Shell did not immediately respond to calls for comment.

Repeated attacks on oil platforms have disrupted oil operations in Nigeria in recent years.
