ISLAMABAD/KABUL: Afghan Taliban leader Mullah Akhtar Mansour was injured in a firefight following a verbal dispute at a meeting of militant commanders in Pakistan, officials said, exposing deep divisions within the fractious militant movement. “Mansour was seriously injured. He was rushed to hospital and we are not sure if he survived his wounds,” Sultan Faizi, the spokesperson for the Afghan first vice president, told AFP. An Afghan intelligence source confirmed his account, and insurgent sources also told AFP Mansour had been injured. Four people were killed in the firefight Wednesday, a Taliban source close to Mansour’s group told AFP, and a number of people injured. “Akhtar Mansour is among the injured but the extent of his injuries is not clear,” he said.
