Hundreds of Taliban insurgents have launched an assault on a remote district in Afghanistan's north-eastern Badakhshan province.
Sakhi Dad Haidari, a deputy provincial police chief in Badakhshan, said the attack started early on Saturday morning in the Yamgan district, a mountainous district with no road leading to it.
Mr Haidari said the police need air support and reinforcements.
Lal Mohammad Ahmadzai, a spokesman for the provincial police chief in Badakhshan, said the insurgents are near the district's headquarters and an intense battle still rages.
Taliban spokesman Zabihullah Mujahid has claimed responsibility for the attack. It comes amid the Taliban's annual warm weather offensive, the first since US and Nato forces ended their combat mission in the country at the end of last year.
