Taliban co-founder Mullah Abdul Ghani Baradar arrived in Kabul on Aug. 21 for talks on establishing a new "inclusive" government in Afghanistan, a senior official said.
Other senior Taliban leaders seen in the capital in recent days include Khalil Haqqani - one of America's most wanted terrorists with a $5 million bounty on his head.
Turkey helped a number of senior former Afghan government officials leave the country after the capital Kabul fell to the Taliban.
As the turmoil gripped the country, Ankara made arrangements to repatriate Turkish citizens from Afghanistan.
As part of those plans, a plane belonging to Turkish Airlines was dispatched to Kabul to airlift Turkish citizens.
