Ten policemen were killed and eight others injured after four insurgents attacked Logar's police headquarter and began clashing with the security forces, local officials said.
The attack took place at about 12 p.m. after two suicide bombers detonated their explosives inside the building and another detonated his explosives inside the chow hall, while the other insurgent was shot dead by security forces after a long two hour clash, Provincial Governor Spokesman Din Mohammad Darwish said.
"The insurgents had the police uniform on and were able to enter the building," Darwish said. "The injuries of the police are very critical."
The Taliban insurgents have claimed responsibility for the attack.
