Afghanistan's president is denying he met with a senior Taliban leader. Officials familiar with the Afghan government's reconciliation efforts with the Taliban say a man involved in the secret talks who claimed to be one of the Taliban's top commanders was actually an impostor. News reports quote unnamed officials as saying the man claiming to be Akhtar Mohammad Mansour was a fraud. The New York Times newspaper reports that NATO and Afghan officials said they held three meetings with the man. Officials said he was even flown on a NATO aircraft to the Afghan capital, Kabul, to meet with President Hamid Karzai. President Karzai told a news conference in Kabul Tuesday that he never met Mansour. Karzai did not say whether he met with a person who claimed to be Mansour. Reports of the impostor raise doubts about the state of efforts to resolve the nine-year war in Afghanistan. Last week, Afghan Taliban leader Mullah Omar denied that his group was negotiating a peace agreement with the Afghan government. Omar called reports of talks "baseless propaganda" designed to cover up what he called the failure of U.S.-led forces in Afghanistan. The alleged impostor reportedly came from Pakistan, but his identity and possible motivation for posing as the Taliban commander are unclear. Some Afghan officials suspect he might have been sent by Pakistan's intelligence service, the ISI. The New York Times was the first to report the story about the fake leader in an article published Monday. Some information for this report was provided by AP. .
