KALAT: Levies recovered four bullet-riddled bodies in Balochistan's Kalat district on Friday evening.

Levies sources said the bodies were found in the Nimargh area of Kalat district. All the victims had received bullet injuries.

The bodies were shifted to District Headquarters (DHQ) hospital in Kalat. Levies personnel reached the scene as an investigation into the incident went underway.

There was no immediate claim of responsibility for the killings.

In a separate incident, unknown miscreants blew up an eight-inch gas pipeline in Balochistan's Dera Bugti. Levies sources said gas supply from well number 7 was suspended following the incident.

"They planted an improvised explosive device near the gas pipelines, which went off with a large explosion," said Levies sources. Repair work to restore gas supply could not be immediately started due to the risk of landmines in the area.

"Repair work will be started once the area is cleared by security personnel."

Militants have conducted attacks against security forces and national installations in Balochistan, which has been plagued by an insurgency and growing sectarian killings for more than a decade.
