Six police also died and 10 intelligence officers were wounded in the attack on the Khwaja Omari district headquarters in the southeastern province of Ghazni, the provincial governor's spokesman Aref Noori told AFP.
Mohsini put the death toll at 13, including the governor, police and intelligence officers, adding scores of Taliban fighters were also killed but that could not be immediately confirmed.
Afghan officials often give conflicting casualty figures immediately after an attack.
"The attack is over and the district is under the control of Afghan security forces after reinforcement forces rushed to the scene following the Taliban attack," Mohsini added.
The Taliban claimed responsibility for the raid in a WhatsApp message to journalists, saying "more than 20 police" were killed and several others wounded. "Our mujahideen have confiscated weapons and ammunition," Taliban spokesman Zabihullah Mujahid said.
"In the attack three mujahideen were martyred and four others were wounded." The attack was one of the deadliest by the Taliban in several weeks and comes as the militants prepare to launch their annual spring offensive, which marks the beginning of the traditional fighting season.
The militants had vowed to take revenge over an Afghan air strike last week in an area controlled by the group in the northern province of Kunduz.
