JOIN USZabiullah Mujahid, a Taliban spokesman dismissed as "totally" false the report that Omar was shot dead as he was being moved from Quetta to North Waziristan by former ISI chief General Hamid Gul.
"We totally deny such reports that get published by our enemies and then other media publish the same baseless reports," Mujahid, was quoted as saying by New York Times.
Former ISI chief Gul also vehemently denied that he was with Omar. Laughing at the reports and calling them completely baseless, he remarked "Was I killed too?" and "Am I speaking to you from heaven?"
General Gul said he was in Rawalpindi two days ago, though it was not clear whether the Afghan security directorate believed he was physically with Omar or was orchestrating the move from elsewhere.
Earlier, Afghan channel TOLO news reported quoting a source in the Afghan National Directorate of Security that Omar was killed in Pakistan.
According to the source, Omar has been killed two days ago. But there was no official confirmation of the report and as to who killed him.
American intelligence officials suspect Omar and other senior Taliban leaders have been safely harbored for years in Quetta with the support of part of the Directorate for Inter-Services Intelligence, the military spy service formerly headed by Gul, who insisted he has never met Mullah Omar.
German Brig. Gen. Joseph Blotz, chief spokesman for the NATO-led International Security Assistance Force in Kabul, said NATO was looking into the reports of the Taliban leader's death but could not confirm it.
"We do not know if it is true or not," he said.
