Gen. Mohammed Sharif Amin, police chief for Nangarhar province, said two of the militants detonated their explosives-filled vehicles in front of the Jalalabad Quick Reaction Force headquarters, allowing six attackers in a third vehicle to enter the compound, the Los Angeles Times reported.
As the driver detonated the explosives in the third car, five assailants rushed the compound and opened fire on police, and were killed during an exchange of gunfire, Amin said.
Four other police officers were wounded, officials said.
It wasn't clear whether the attackers on foot detonated their suicide vests before they were killed by police, the Times said.
