A powerful bomb exploded Saturday at a bus station in northwest Pakistan, killing five people and wounding three others, police said.

The remote-controlled bomb in the northwestern town of Kohat struck a moving bus when hundreds of passengers were gathered at the station to leave for different cities to celebrate the Muslim festival of Eid al-Adha, senior police officer Ishtiaq Marwat said.

Footage from Pakistani news channels showed the damaged bus.

No one claimed responsibility for the attack, though Kohat has been the scene of sectarian attacks in recent years, most blamed on Pakistani Sunni Muslim militants.

Kohat is located about 50 kilometers (30 miles) southwest of Peshawar, the capital of Khyber-Pakhtunkhwa province.

Also Saturday, a roadside bomb exploded near a livestock market in the southwestern city of Quetta, wounding five people, police officer Mohammed Ishaq said.

Quetta is the capital of southwestern Baluchistan province, where nationalists are waging a low-scale insurgency. Small separatist groups are also active in the province and they often claim responsibility for such attacks.
