Police say a roadside bomb targeting a security convoy has killed at least one civilian and wounded eight others in southwestern Pakistan.

Senior police officer Abdul Majid Bhatti says no soldiers were hurt in Tuesday's attack on the outskirts of Quetta, the capital of Baluchistan province.

He says the civilians who were killed and wounded were passing through the area in their vehicles at the time of the blast.

No group claimed responsibility, but suspicion fell on nationalists who have waged an insurgency in Baluchistan for decades to get greater autonomy and a larger share of the province's natural resources. They often target Pakistani security forces.
