Suspected Taliban suicide fighters were engaged in a gun battle with Afghan police inside a base near the Pakistan border on Friday, officials said.
Local officials in Urgun, in the southeastern province of Paktika about 200 km (125 miles) south of Kabul, said an unspecified number of Taliban fighters had stormed a police post after detonating a bomb near the entrance.
One official said Taliban commandos with small arms and grenades were holed up in the base but were being rooted out by police.
Further details, including the numbers involved or any casualty figures, were not immediately available.
