The Afghan Taliban on Saturday denied that their leader Mullah Omar had written to President Barack Obama last July.
Taliban spokesman Zabiullah Mujahid said reports that Omar had sent a letter indicating an interest in talks key to ending the war in Afghanistan were "baseless allegations."
"The Islamic Emirate of Afghanistan is strongly condemning these rumors and allegations," Mujahid said in an email to media organizations, referring to the Taliban by the name Afghanistan had while under their rule.
He added that the reports were aimed at sowing confusion among Afghans.
Current and former U.S. officials told The Associated Press the letter purportedly from Omar was unsigned. It was passed through a Taliban intermediary and intended for the White House. The officials spoke on condition of anonymity because the letter and its contents are part of sensitive diplomacy with a fighting force that still targets U.S. troops.
The previously undisclosed communication was considered authentic by people who saw it, but skeptical administration officials said they cannot determine it actually came from Omar.
The Obama administration did not directly respond to the letter, two officials said, although it has broadened contacts with Omar's emissaries since then.
Sources who described the letter did not disclose its precise contents, but one current and one former official said it addressed Taliban willingness to build trust with the United States. One official said Omar complained that the United States had not done enough to establish good faith for negotiations, such as arranging the release of Taliban prisoners held in the U.S. military prison at Guantanamo Bay, Cuba.
An administration official would say only that the message represented views consistent with what Taliban emissaries had been telling U.S. officials during the clandestine meetings. Those preliminary sessions opened the way for more formal talks that U.S. officials now publicly welcome.
A direct message from Omar could be a strong signal that the Taliban movement is interested in negotiation at the highest levels.
The Obama administration is trying to foster talks among the Taliban and the US.-backed government of Afghan President Hamid Karzai, but remains wary of Taliban motives.
Omar is the spiritual leader of the Taliban movement, and directs the organization's guerrilla military campaign. He was the de facto head of state in Taliban-controlled Afghanistan prior to the U.S. invasion that toppled the Taliban government in 2001. He has not been seen in public in years, and his exact whereabouts are unknown. He is wanted by the U.S. government for harboring Osama bin Laden and helping the al-Qaida terror network.
The Obama administration is now considering release of five top Taliban leaders from Guantanamo as a starting point for negotiations. The five would be sent to custody in the Gulf nation of Qatar, where the Taliban plan to establish a negotiating office. Republicans in Congress oppose the release of the prisoners.
