PESHAWAR, Pakistan -- A suicide bomber riding on a motorcycle attacked a vehicle carrying a deputy commander of police in northwestern Pakistan on Thursday, killing two policemen and wounding three others, police said.

The deputy commander, Malik Tariq, was among those wounded in the attack in Peshawar, the city's police chief Mian Muhammad Saeed said.

He said the attacker blew himself up as 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, without providing further details. Pakistan launched a major offensive a year ago in North Waziristan, a longtime haven for the Pakistani Taliban and other militant groups.

The military says the operation has killed over 1,300 militants since then and that 90 percent of the region has been cleared of insurgents. Journalists have virtually no access to the mountainous region along the Afghan border.(AP)
