A police official says a suicide bomber has blown himself up near a police van in northwestern Pakistan, killing at least two people.

The official, Zaheer Khan, says Tuesday's attack in the district of Bannu in the Khyber Pakhtunkhwa province bordering Afghanistan also wounded at least 10 people.

He says initial reports suggest the attacker was on foot and targeted a police van near a police station.

Khan says rescuers were transporting the dead and injured to a nearby hospital.

No one immediately claimed responsibility for the attack but suspicion fell on Pakistani Taliban who often target police and security forces deployed there.

The district of Bannu is located just outside the North Waziristan tribal region where several Pakistani, Afghan and al-Qaida-linked militant groups are based.
