Police in southwestern Pakistan say two soldiers were killed and at least 10 people were wounded when a car bomb targeted a military convoy.

The police say the blast occurred Monday in Quetta, the capital of southwestern Baluchistan province.

No one has claimed responsibility for the bombing.

Baluchistan is home to various militant groups, including pro-Taliban factions, and Baluch separatists who are fighting a low-level insurgency in hopes of gaining political autonomy and a greater share of the profits from the region's natural resources.

Amnesty International says Baluchistan is one of the most militarized regions of Pakistan, where armed sectarian groups, government security forces and criminal gangs operate with impunity.
