Some 50 extremists attacked the plant of MOL Pakistan Oil and Gas company, a member of the MOL group, in Hangu district, near the Afghan border, police spokesman Ifran Hahn said.

So far, no terrorist groups have taken responsibility for the attack, and the MOL subsidiary has been unavailable for comment.

MOL told MTI in a statement that none of the company’s employees had been present at the plant at the time of the attack.

Production at the plant has been temporarily suspended via remote control and switched to back-up safety mode, the company said.
