Pakistan 'bomb blast wounds 13'

Pakistani police say a bomb has wounded 13 police and soldiers in the south-western city of Quetta.

Those injured were travelling in a truck when the blast occurred. Police have yet to identify the attackers.

One report said a bomb on a bicycle had been detonated by remote control; another said a grenade was thrown from a motorcycle.

Quetta has been a target for Islamic militants - in March over 40 people died in an attack on Shia Muslims.

Injuries 'not life-threatening'

Balochistan Province chief of police Shoaib Suddle told reporters seven of the injured belonged to the paramilitary frontier constabulary. The other six were from the provincial reserve police.

He said all the injured were being treated at a local hospital, and none of them had life-threatening wounds.

In recent months, there have been several incidents in which low-intensity homemade bombs have gone off in Quetta, or rockets have been fired into the city, targeting government installations.

Earlier this month, a bomb explosion in Balochistan's port city of Gwadar killed three Chinese engineers, and injured several others.

But so far the authorities have not been able to establish which group or individuals are behind the attacks or ascertain what their motive might be.
