A suicide blast in southwestern Pakistan Saturday injured at least six people, including three Chinese engineers, while unknown gunmen killed three policemen in a northern region bordering China.

Authorities in restive Baluchistan province confirmed a team of Chinese workers was returning from a mining project when the bomber detonated his explosives-laden vehicle near their bus, just outside the town of Dalbandin.

The bus driver and two local paramilitary troops guarding the foreigners were also among those injured. Local officials said none of the victims received life-threatening injuries and they all “are in stable condition.”

Area police said that paramilitary forces were leading a search operation to look for suspected facilitators of the attack. A separatist group, called Baluchistan Liberation Army (BLA) has claimed responsibility for the violence.

China condemned the attack on its citizen. The Chinese side has requested that the relevant Pakistani departments investigate the incident, bring the perpetrators to justice and take further effective measures to ensure the security of the Chinese institutions and citizens in Pakistan,” according to a Chinese embassy a statement.
