The man was critically injured in the first blast and later died of his wounds. When labours working nearby gathered around the explosion site, another blast occurred, though no loss of life was reported, reports Dawn News.

Officials told Dawn News unidentified miscreants used an improvised explosive device (IED) for the blasts.

“The IED was planted close to the under-construction watchtower,” a Levies official told Dawn News, adding that a civilian, identified as Zhob’s resident Muhammad Usman, lost his life after being critically injured.

Security officials and coal miners working in a nearby field rushed to the spot following the blasts.

“It seems the miscreants detonated both IEDs with a remote control,” a Levies official told Dawn News, adding that an investigation into the incident was underway.
