A bomb exploded near a police station and assailants fired rockets at paramilitary troops in attacks in southwestern Pakistan (search), police said Sunday. No injuries were reported.

The bomb shattered windows Saturday night at the police station in Mach, a town near Quetta (search), capital of the restive Baluchistan (search) province, according to a provincial police chief. In two other attacks the same night, assailants fired rockets at paramilitary troop in the towns of Mand and Kohlu, but the rockets missed.

Mir Azad Baluch, (search) a man claiming to speak for the Baluchistan Liberation Army, claimed responsibility for the two rocket attacks. The group has claimed responsibility for previous attacks in the southwestern province.

Baluchistan has been the scene of small-scale bombings and rocket attacks in recent months. The violence is blamed on local tribesmen who are suspected of using attacks to push the government for more royalties from natural gas and other resources taken from the province.

The attacks came a day after a homicide bomber struck at a Muslim shrine near the diplomatic enclave in Pakistan's capital, Islamabad, killing at least 20 Muslim worshippers. Police are trying to determine the identity of the suicide bomber. There was no indication that violence and Saturday's attacks in Baluchistan were related.
