The Pakistani Taliban has denied that the leader of their Swat faction was killed in a clash with the Afghan Taliban earlier this week.
According to the report by the BBC, at least three Swat Taliban commanders were killed during the clash in the northeastern Kunar province of Afghanistan two days earlier.
The report said some sources also alleged that Swat Taliban chief Maulana Fazlullah was killed in the attack, Dawn News reports.
The Pakistani Taliban, however, denied this claim.
Mullah Fazlullah, 39, had unleashed a reign of terror in Swat before he lost control of the area following a military operation, the report said.
He fled to Afghanistan and is believed to operate primarily from that country's Kunar and Nuristan provinces, from where his men attack Pakistani forces, it added.
