KABUL: A man leading the Taliban side of peace talks with the Afghan government was an impersonator, an Afghan close to the negotiations said Tuesday, an embarrassing revelation for Afghan officials who have promoted reconciliation efforts as the best chance for ending the war. Quickly moving to do damage control, President Hamid Karzai dismissed the reports as “propaganda,” saying neither he nor any other members of his government had ever met with a man named Mullah Akhtar Mohammad Mansour -one of highest ranking members of the Taliban council. The report about the impostor first appeared in The New York Times and the Washington Post. Karzai denied that anybody named Akhtar Mohammad Mansour was ever brought by NATO to Afghanistan for meetings with him and other officials.
