At least 12 security force members were killed in an attack by the Taliban on Bala Hisar military base in Imam Sahib district in the northern province of Kunduz on Thursday night, sources said.

The sources added that 11 security force members were wounded in the attack. 

Meanwhile, two police force members were killed when they were on their way to the army base to help the forces when their vehicle hit a roadside bomb in which two others were wounded, the sources said.

The military base, which is a key base in the northern province, fell to the Taliban for some hours but was retaken by the security forces, the sources said.

The sources said that at least 10 Taliban members were killed or wounded in the attack, but the Taliban has not commented on the incident.

This comes as a military base was targeted by a car bomb attack in Paghman district, Kabul province, on Friday morning, killing two security force members and wounding two others. 

Violence remains high in the country in recent weeks despite efforts to start peace negotiations in Doha.
