"There is no truth to the rumours that I was injured or killed in Kuchlak (near Quetta in Pakistan)," said the more than 16-minute long audio file, emailed to media by a Taliban spokesman yesterday.
"This is enemy propaganda... I haven't seen Kuchlak in years."
Afghan intelligence officials and multiple insurgent sources had claimed that Mansour had been seriously injured in a heavy exchange of fire at a gathering of militant commanders on Tuesday.
Vehement denials by the Islamist group of any shootout fell on sceptical ears, especially after they kept the death of longtime chief Mullah Omar secret for two years.
Mansour was declared Taliban leader on July 31 after the insurgents confirmed the death of Omar, who led the Islamist movement for about two decades.
But splits immediately emerged in the group, with some top leaders refusing to pledge allegiance to Mansour, saying the process to select him was rushed and even biased.
