At least six people have been killed and more than 30 wounded in a bomb blast near a police station in Quetta, the capital of Pakistan's Balochistan province.

An official from the bomb disposal squad said on Thursday that a bomb planted on a motor bike exploded.

The blast also damaged several shops and vehicles parked in the market in the troubled region where separatists have been fighting against the government troops. No one has claimed responsibility for the attack.

Earlier in the day, two different blasts occurred in the cities of Lahore and Peshawar, Al Jazeera's Hameedullah Khan reported.

In Lahore, officials confirmed that the blast hit popular Anarkali bazaar killing one and wounding 13 others.
