At least three security personnel were killed on Friday in a bomb attack on their vehicle in southwestern Pakistan, officials said.
Militants targeted the vehicle of a local administrator in Pishin area of Balochistan.
Additional Deputy Commissioner Pishin Waqar Khursheed said that the apparent target of the attack was an assistant commissioner but he was not in the vehicle.
"Three police officials were killed in the attack," Khursheed said.
No one claimed responsibility for the assault but Taliban militants and Baloch nationalists have been involved in such attacks in the past.
