Seven persons lost their lives in a blaze that engulfed multiple vehicles as a van carrying petrol collided with a truck in Mach, Balochistan on Tuesday.
The collision triggered fire in the van, burning all seven passengers to death.
Police said the driver was hiding smuggled petrol in a make-shift tank in the van, and they have cordoned off the area to probe into the incident.
At least three other vehicles that were parked near the incident site also caught fire.
Two policemen who were posted at the Mach check post also suffered burns while trying to put the fire out, local police said.
The bodies of the deceased have been shifted to hospital as authorities mounted a rescue operation.
The incident also resulted in closure of the national highway for many hours.
The accident occurred a day after 20 people were killed when two buses collided head on in Pakistan’s Punjab province that also left 30 others injured.
