Taliban supreme leader Mullah Mohammed Omar retains control of his stronghold Kandahar and is believed to remain in the city, a spokesman for an opposition Afghan faction said Friday.

Several Afghans, some of whom were in contact with Taliban commanders, confirmed that Omar was still in charge and had not relinquished power despite persistent, unconfirmed reports to the contrary, said the spokesman, Ahmed Karzai.

Karzai, whose brother Hamid is believed inside Afghanistan organizing resistance to the Taliban, said his assessment was based on reports from trusted Afghan sources who arrived in Quetta on Thursday and Friday.
