QUETTA, Nov 22: Over 100 industrial units were closed in Hub as power to the entire Lasbela district was suspended after a pylon of high-power transmission line supplying electricity from Karachi was blown up on Thursday.

“The entire Lasbela district was plunged into darkness after the huge tower of the 132,000kV transmission line was blown up on the Sindh-Balochistan border,” a police officer told Dawn.

“Production stopped in all industrial units in the Lasbela Industrial Estate and ship breaking work was suspended in Gadani.

Karachi Electric Supply Company sources said restoration of power supply after replacement of the destroyed pylon would take at least a week.
