Col Asadullah Ensafi, the deputy police chief in Ghazni province, said today another 15 police officers were wounded in the attacks on police checkpoints in the province's Andar and Qarabagh districts.
The Taliban claimed responsibility for the attacks, carried out yesterday. Insurgents have targeted police checkpoints targeted in recent months, resulting in high casualties.
Separately, Ensafi says an Afghan airstrike killed 16 insurgents and wounded 17 late yesterday in Ghazni's capital.
The war with the Taliban has been particularly tough this year for Afghan forces, who are fighting without international troops backing them up following the US and NATO ending their combat mission last year.
