Quetta, Pakistan: A rocket struck a police vehicle in the southwestern Pakistani province of Baluchistan on Thursday killing four policemen, officials said.
The incident took place near the remote town of Musa Khel, some 350 kilometres (217 miles) east of Quetta, the provincial capital of Baluchistan.
"Four policemen, including the local police station chief were martyred in the rocket attack on their vehicle," senior district official Hashim Fuwad Rabbani told AFP.
Akbar Hussain Durrani, the top bureaucrat of home department, confirmed the casualties and said that paramilitary forces have been sent into the area to hunt the attackers.
Nobody immediately claimed the responsiblity for the attack, but tribal rebels demanding more control over region's rich oil, gas and mineral resources have waged an insurgency and frequently attack government and military targets.
Baluchistan province is also wracked by Taliban attacks and sectarian violence.
