Reports that Mullah Mohammad Omar have been met with scepticism in the Pakistan military ahead of with peace talks with the Afghan government.
A senior official from the Pakistani military, which historically has close ties to the Afghan Taliban and other Islamist militant groups in the region, said he could not confirm Omar's death.
"It is worth asking why this news has come out now, when we are two days away from the second round of peace talks," said the official.
"Especially in light of reports that he died two years ago... why is this news being released now? It raises questions about the intentions of people who don't want talks to go forward."
