Victims were riding in an oil company vehicle

Islamabad: Four people were killed in a bomb attack yesterday in a remote district of Pakistan's southwestern Balochistan province, police said. The province is plagued by a low-scale insurgency involving Baloch separatists.
The bomb, which police said was fastened to a motorcycle, was detonated by remote control and targeted a vehicle of the state-run Oil and Gas Development Corporation in Dera Allahyar area of Jaffarabad district, killing four workers of the corporation.
The district is about 270 kilometres southeast of Quetta, the capital of Balochistan and borders both Afghanistan and Iran.
On Wednesday an activist of the main opposition Pakistan Muslim League-Nawaz (PML-N) party, was reportedly gunned down outside his office in Quetta.
In the northwest, a Nato oil tanker on its way to Afghanistan was destroyed by an explosion yesterday in the Khyber tribal region, according to media reports.
The bulk of supplies and equipment required by foreign troops in Afghanistan are shipped through the Khyber tribal region.
Supply trucks and tankers of Nato contractors have been frequently attacked in the region and some political parties have held periodic rallies demanding that the supply line be cut off by the government over the continued attacks by US drones in the tribal areas.
