KUNDUZ, Afghanistan, May 18 (Xinhua) -- About six militants were killed and four wounded after Afghan security forces launched a night raid operation in the country's northern province of Kunduz overnight, a local official said Saturday.

"A unit of army's Special Operation Forces stormed a Taliban hideout in Aaq Masjid locality, on northern outskirts of provincial capital Kunduz city. The security force tried to arrest militants but a clash erupted during the raid, leaving the casualties," provincial government spokesman Esmatullah Muradi told Xinhua.

The security forces arrested three suspected militants and destroyed the targeted hideout along with weapons and ammunition, the official said, adding no member of security force was hurt before they returned to their camp.

Meantime, Zabiullah Mujahid, a purported Taliban spokesman, tweeted that no member of the insurgent group was killed or arrested outside Kunduz city, adding the troops detained three innocent villagers in Aaq Musjid locality of Kunduz.

The province has been the scene of clashes between Taliban and security forces for long.

Fighting rages across the war-torn country and clashes between security forces and Taliban have been continuing in at least 25 out of the country's 34 provinces since early April when Taliban launched a yearly rebel offensive.
