Pakistani police say about 100 militants have ambushed a police station in the northwestern city of Peshawar, shooting dead three officers.
Saeed Khan, a senior police official in the city, says the early Friday attack wounded another nine officers in the Sarband neighborhood on the edge of the city.
He says Sarband borders the Khyber tribal region, an area where many insurgents live.
Khan says he doesn't know what group to which the shooters belong.
The Pakistani Taliban have carried out hundreds of attacks on the country's army and other security forces since 2007.
The attack came a day after militants armed with guns and grenades killed four Pakistani soldiers in an ambush in the South Waziristan tribal area.
