Spokesman of the Quetta Electricity Supply Company (QESCO) Shafqat Ali told this news agency that unidentified men had planted an explosive devise with the 132-KV high transmission line which was detonated blewing up the towers and suspending power supply to many parts of Balochistan.

The saboteur act would cause 120 to 140 MW power shortfall in Balochistan which has already been facing 500 MW electricity shortfall said the spokesman.

He said that a patrolling team of QESCO had already left for the damaged site: however the repair work would be started after security clearance.

Meanwhile, the law enforcers launched search operation in the area to  arrest the accused.

A case has been registered against the unknown miscreants.
