A suicide bomber on a motorcycle has attacked a vehicle carrying police in north-western Pakistan, killing two policemen and leaving three others injured.
Police deputy commander Malik Tariq was among those injured in the attack in Peshawar, the city's police chief Mian Muhammad Saeed said.
He said the attacker blew himself up as Mr Tariq's vehicle passed through Peshawar, the capital of the Khyber Pakhtunkhwa province bordering Afghanistan.
Mohammad Khurasani, a spokesman for the Pakistani Taliban, claimed responsibility and warned of more attacks.
The militant group has spent nearly a decade fighting to overthrow the government and replace it with a hard-line Islamic state.
The military, meanwhile, said a "cordon and search" operation in the nearby North Waziristan tribal region resulted in the killing of 10 militants. No further details were provided.
