Four Taliban militants were killed and another four injured when the NATO-led forces conducted an airstrike against insurgent in Afghanistan's Kapisa province, some 65 km north of the capital city of Kabul, a district administrative chief said on Saturday.

"The international forces launched an airstrike against insurgents in Alasay district in the wee hours Saturday, resulting the death of four Taliban insurgents and injuring four others," Alasay district chief, Mullah Mohammad told Xinhua.

According to initial information, no civilian casualties has been reported in the air raid attack that took place in Bahdur Khil village, the official added.

According to local police sources, a similar attack in neighboring Nijrab district had killed 14 insurgents, including a Taliban deputy shadowy governor for Kapisa province Thursday night.

Taliban militants, Afghan and NATO forces have yet to make comments.

Despite the presence of over 140,000 NATO-led forces, the Taliban-led insurgency has been on rise over the past couples of years especially in south and eastern part of the militancy-hit country.
