Officials in Pakistan say suicide bombers have attacked a police station in the northwest, killing at least six people.
The Pakistani Taliban claimed responsibility for the attack Monday near Bannu.
Authorities say the militants attacked the station using grenades and rockets, sparking an hour-long gunbattle with police. Three of the attackers were killed, but officials say one bomber managed to escape.
Officials say three police officers and three civilians were killed, and that eight other people were wounded.
Bannu is located in Khyber-Paktunkhwa province and at the entrance of North Waziristan tribal agency, a known hub of Taliban and al-Qaida extremists.
A Taliban spokesman said the attack was in revenge for the killing of militant commander Baitullah Mehsud's nephew last month. Mehsud himself was killed in a suspected U.S. drone strike in 2009.
