QUETTA: A remote controlled bomb targeted an Oil and Gas Development Corporation (OGDCL) car in Dera Allahyar, a town in Jaffarabad district, on Thursday killing four, DawnNews reported.

The people who were killed worked for the state-owned OGDCL. In the past, OGDCL interests have been targeted in the province.

There was no claim of responsibility. Both Taliban militants and Baloch separatist nationalists are blamed for violence in Balochistan.

Police said the bomb was fixed to a motorbike and parked on the roadside about 170 miles (272 kilometres) southeast of the provincial capital Quetta.

“It was a remote-controlled device which hit the oil and gas officials' vehicle,” Mohammed Tariq, a senior police official, told AFP.

Balochistan has long been the scene of a low-level insurgency by nationalists who say their movement is aimed at getting a greater share of profits from natural resources like natural gas extracted from their province.
