FARAH, Afghanistan, Jan. 2 (Xinhua) -- A district police chief was killed following an insurgents' ambush attack in Farah, western Afghanistan overnight, the latest in a string of attacks against officials, local police said on Tuesday.

"Mohammad Ibrhim, police chief of Pusht Rod district, was martyred and two police personnel were wounded in a gunfight late Monday night in surrounding areas of the district after the unit was responding to a Taliban insurgent's ambush attack there," provincial police spokesman Iqbal Bahir told Xinhua.

The attack occurred when Ibrahim was monitoring security checkpoints in the district, north of provincial capital Farah city, 695 km west of Afghan capital of Kabul, and the injured were shifted to a hospital by a responding unit of police force, the source noted.

Taliban militants, who ruled the country before being ousted in late 2001, renewed armed insurgency, killing government troops as well as civilians.

The attack came as Afghan and coalition forces continued mopping-up operations against Taliban and Islamic State (IS) fighters.
