ISLAMABAD, Pakistan (CNN) -- A top Taliban aide has acknowledged that the leader of the Pakistani Taliban, Baitullah Mehsud, is dead.

The Taliban had previously denied reports that a U.S. missile strike killed Mehsud.
A close aide to two senior Taliban leaders, however, said Mehsud is dead but declined to comment on the circumstances surrounding his death. He spoke on the condition that his name not be used.
They have said they were awaiting DNA tests for confirmation.
Over the weekend, a Taliban official said Taliban commander Hakeemullah Mehsud was selected the new head of the Pakistani Taliban.
Hakeemullah Mehsud was selected Friday by a 42-member Taliban council, or shura, according to Taliban commander Qari Haris.
