Pakistani police say two people were killed and 10 wounded when a bomb planted on a bicycle exploded in southwestern Pakistan.

The device exploded on a road near Quetta, the capital of restive Baluchistan province, as a military convoy passed by. Some of the people injured were paramilitary soldiers. Vehicles were also damaged in the blast.

There was no immediate claim of responsibility.

Baluchistan has been the scene of sectarian violence, militant attacks and unrest linked to a low-level insurgency. Baluch rebels have been fighting for political autonomy and a greater share of the province's natural resources.
