Mansour was critically wounded in a gunfight on Wednesday after a bitter argument with commanders in the militant group, Sultan Faizi spokesman for the first vice president said.
The incident came as the Taliban has been divided into two factions after Mansour succeeded former Taliban leader Mullah Mohammad Omar as the hardliner group’s leader after Omar was confirmed dead in late July.
Mullah Akhtar Mansour was reportedly injured a few days ago in a firefight following a verbal dispute at a meeting of militant commanders in Quetta of Pakistan.
Sultan Faizi said following the incident he was rushed to a nearby hospital.
The meeting was at the home of Abdullah Sarhadi, a commander in Mansour’s group and a former Guantanamo Bay prisoner who had been arrested after 2001 by the US, then released, the Taliban sources said.
He was arrested again later on by Pakistan, then released sometime in 2012, they said.
“There were differences on some points which later turned into harsh words, then Sarhadi opened fire and the others returned fire,” the Taliban source said.
However, Taliban spokesman Zabihullah Mujahid denied such reports.
