Five senior members of the Taliban have agreed to a transfer to Qatar as part of a peace deal.
Afghan government officials announced the agreement after meeting the prisoners earlier this week on a visit to Guantanamo Bay.
The US has not yet approved the transfer but is considering it as part of ongoing attempts to engage in negotiations with the Taliban.
White House spokeswoman Caitlin Hayden said:
"The United States has not decided to transfer any Taliban officials from Guantanamo Bay.
"We are not in a position to discuss ongoing deliberations or individual detainees, but our goal of closing Guantanamo is well established and widely understood."
Qatar is playing an increasingly important role in negotiations, with the Taliban confirming the opening of an office in Doha last January.
