Gunmen shot dead the driver of a truck carrying supplies for NATO troops in Afghanistan and a police official in separate attacks in Pakistan's southwest on Sunday, police said.
Suspected tribal rebels in insurgency-hit Baluchistan province gunned down the driver of a truck carrying supplies for NATO soldiers across the border in Afghanistan and wounded his helper, police officer Mohammad Sarwar said.
Separately, a police official was killed and two others wounded when assailants opened fire on their vehicle in another district of Baluchistan, local police officer Shariq Jamal said.
The police van was on a routine patrol, he said.
Hours later a nationalist group, the Baluch Republican Army, claimed responsibility for that attack.
Baluchistan has been rocked by a four-year insurgency waged by tribal rebels fighting for political autonomy and a greater share of profits from the region's natural resources.
The province has also been hit by attacks blamed on Taliban militants.
