NATO troops Thursday night arrested six Taliban commanders, including a high ranking leader Mullah Abdul Hai Motmahen, during an operation in Ghazni province in south Afghanistan, a local official said Friday.

"Six Taliban commanders including Mullah Abdul Hai Motmahen were arrested in Andar district of Ghazni province last night," district governor Sher Khan Yusufzai told Xinhua on Friday.

NATO troops and Taliban militants have yet to make comment.

A well known Taliban commander, Mullah Abdul Hai Motmahen, was a political and military leader during the Taliban regime, and remains in close relationship with Taliban supreme leader Mullah Omar.

After the collapse of the Taliban regime in 2001, he became the main commander of Taliban insurgents in Ghanzi province. His arrest is believed to be a major setback for Taliban militants.
