The Express Tribune quoted the officials as saying that FC's patrolling team asked the driver of the tanker to stop, but its driver ran over their vehicle in a bid to run away.
"The Frontier Corps soldiers attempted to intercept the oil tanker, but the driver ran over their vehicle, killing five personnel, including a Naib Subaidar," the officials said.
Balochistan Chief Minister Nawab Sanaullah Zehri has ordered a probe into the matter.
Last week, three FC personnel were killed in a blast in North Waziristan's Ghulam Khan area.
According to Dawn, an improvised explosive device (IED) blast took place targetting the personnel's vehicle when they were patrolling in the area.(ANI)
