Deadly blast in Pakistan

At least three people were killed and dozens more wounded when a bomb ripped through a bus in the Pakistan city of Quetta.

University students were on the bus when the remote-controlled bomb planted in a car went off nearby.

Students and pedestrians were among the wounded.

Several militant groups are active in Baluchistan - Pakistan's biggest but poorest province.

Much of the violence has been blamed on Baluch separatists, while pro-Taliban militants are also active in the province.

Sunni Muslim militants have also stepped up attacks on Baluchistan's Shi'ite minority in recent months.
