Four students killed by 'motorcycle bomb' in Pakistan

A motorcycle bomb has ripped through a university bus in south western Pakistan, killing four students and injuring 50 people, a police spokesman said.

Qazi Abdul Wahid said today's bombing targeted a bus belonging to the Baluchistan IT university.

The attack took place in a neighbourhood of the provincial capital, Quetta.

Mr Wahid would not say who was suspected in the attack but security agencies hold Baloch nationalists responsible for such bombings.

Baluchistan has witnessed a decades-long insurgency by renegade tribal elders and Baloch nationalists who demand greater autonomy and a larger share of the province's resources such as natural gas and minerals.

The province borders Afghanistan and Iran and is also believed to be a refuge for Taliban and Pakistani militants.
