The Taliban held talks with United States officials in Qatar on ending the Afghan conflict last week, the militants confirmed Monday, but said no agreement was reached on "any issue".
Last week, a five-member Taliban delegation had attended talks in Moscow for the first time at an global conference to discuss the Afghan peace efforts.
The US envoy, Zalmay Khalilzad, who is in Kabul to lead talks between the United States, the Taliban and the Afghan government, told local reporters that "he hopes a peace deal is reached before April 20 next year".
Senior Taliban officials met with a "high-ranking" U.S. delegation in Qatar on November 14, 15 and 16, the militant group said in a WhatsApp message, without mentioning Khalilzad.
The top U.S. military officer said Saturday that the Taliban "are not losing" in Afghanistan, and much more needs to be done to bring peace to the war-torn country.
At a meeting with several civil society organizations on Saturday, Ghani said the Afghan youth needs to play a significant role in the peace process as any achievements, or otherwise, will affect them in the long term, the presidential palace said in a statement.
The flag has since been taken down and the office has been empty with no official announcements about a possible reopening.
The Taliban spokesman was not immediately available for comment but two senior Taliban leaders, speaking on condition of anonymity, said the Taliban leaders will present a new set of demands to Khalilzad. "Taliban leaders have not agreed to any deadline because we are winning on all fronts", he added.
In an extraordinary series of meetings over the course of this week, Ghani separately spoke about the board with Gulbuddin Hekmatyar, leader of the Hezb-e-Islami party; Atta Mohammad Noor, Salahuddin Rabbani, and Ismail Khan, leaders of the Jamiat-e-Islami party; Abdul Rab Rasul Sayaf, a former Jehadi leader; and Vice President Abdul Rasheed Dostum, among other influential figures.
Khairkhwa and Fazl were among five senior Taliban members released from the US military detention facility at Guantanamo Bay, Cuba in 2014 in exchange for a captured USA soldier, Bowe Bergdahl.
The Trump administration now appears focused on reaching a political settlement with the Taliban, beginning with the holding of direct talks.
The insurgents, fighting to expel foreign forces and defeat the Western-backed Afghan government, last month presented demands to Khalilzad that included a timeline for the withdrawal of USA troops and the release of senior Taliban from jails.
The U.S. has about 14,000 troops in Afghanistan.
