Talks on an agreement between the United States and Afghanistan ended on Monday.
Talks were being held to end the longest war.
Both sides consulted their leaders on the next steps for a pact to allow the U.S. to withdraw its troops from Afghanistan.
Talks ended without agreement.
The chief U.S. negotiator Afghan-American diplomat Zalmay Khalilzad said on Sunday hard work is being done for a lasting and honourable peace agreement.
Negotiations held in Qatar have brought hopes for an agreement allowing US troops to leave in exchange for a Taliban promise that Afghanistan will not be used as a base for attacks against the United States.
The war has become a stalemate with neither side able to defeat the other.
