The U.S. Special Adviser for Afghanistan Reconciliation Ambassador Zalmay Khalilzad has reportedly met with the political leaders of the Taliban group in Qatar.

A source privy of the development has told The Wall Street Journal that Ambassador Khalilzad on Friday met with the Taliban political leaders in Doha, the capital of Qatar.

The source has not disclosed further information in this regard and it is yet not clear which important topics were discussed during the meeting.

This comes as senior U.S. State Department official had met with the Taliban political leaders in Qatar nearly four months ago.

However, sources within the Taliban ranks have told NBC News that the youngest son of the feared Haqqani terror network’s founder is among hundreds of prisoners whom the Taliban is demanding be released as part of an upcoming round of talks with the United States.

“This meeting with the U.S. authorities would either help pave the way for more meaningful talks or stop them forever,” a Taliban commander in Afghanistan’s Helmand Province said on the condition of anonymity because he was not authorized to speak to the news media. “If they are sincere in talks in the future, they would accept our proposal for a prisoners’ exchange.”
