Clashes between Afghan police and anti-government militants left two rebels dead and seven others wounded in Afghanistan's eastern Paktika province, provincial governor Akram Khapalwak said Monday.
The incidents took place in the districts of Barmal and Gomal along the border with Pakistan, he added.
"Taliban militants attacked police checkpoints in Bermal and Gomal districts Sunday night and police encountered. As a result two rebels were killed and seven others were wounded," Khapalwak told Xinhua.
Two policemen also sustained injuries during the fire exchange which lasted for about one hour, he added.
Meantime, a statement released by the U.S.-led coalition forces here said that the personnel of Afghan army and police backed by the coalition's air power defeated Taliban fighters in Bermal district Monday.
However, it did not give more details on whether there were any casualties on militants side.
Nearly 4,000 people, mostly militants, have been killed in Taliban-linked insurgency so far this year in Afghanistan, according to officials.
