A group of five key Taliban group leaders, who were released for a captive U.S. soldier in 2015, have reportedly joined the Taliban political leaders in Qatar as efforts are underway for the revival of Afghan peace talks.

A Taliban spokesman Zabiullah Mujahid has confirmed to Associated Press that a group of five Taliban leaders have arrived in Qatar and joined the Taliban political leadership in their office in Qatar.

Mujahid has also confirmed that the five Taliban leaders have previously served in Guantanamo detention facility.

In the meantime, reports indicate that the Taliban leaders have joined the political leadership of the group in Qatar with an aim to participate in peace talks.

The five key Taliban leaders who have recently travelled to Qatar, include Mullah Noorullah Noori, Mullah Khairullah Khairzada, Mullah Abdul Haq Wasiq, and Mawlavi Mohammad Nabi Omari.

This comes as the U.S. Special Envoy for Afghanistan Reconciliation Ambassador Zalmay Khalilzad had met with the Taliban political leaders in Qatar three weeks ago.

The Taliban spokesman Zabiullah Mujahid had also confirmed the meeting and had said that the two sides have agreed to continue negotiations in a bid to find a solution for the existing issues.
