Police say militants have attacked a government center in eastern Afghanistan, triggering a gunbattle that killed one police officer and wounded three civilians.

The attack took place early Monday in the Qarabagh district of Ghazni province. Four militants were also killed as security forces repelled the assault on district government offices.

The fighting comes the day after six suicide bombers attacked the compound of the governor of Parwan province, killing 22 people.

Taliban militants claimed responsibility for Sunday's attack.

Insurgents have been increasingly targeting Afghan government officials in recent months.
