The leader of Syria's jihadist al-Nusra Front is in good health, said a statement released by the group on Saturday, denying state television reports claiming his death Al Arabiya reported.
"What was claimed by one channel alone, regarding what it claimed was the killing of the emir of al-Nusra Front, was a lie," said the group.
The Syrian state television reported on Friday that Abu Mohammed al-Jawlani had been killed in coastal Latakia province.
But state news agency SANA quickly withdrew an alert saying the same thing.
The Britain-based Syrian Observatory for Human Rights, which closely monitors the fighting in Syria, said senior Nusra Front leaders contacted by activists in Latakia and the eastern Deir el-Zour province denied al-Golani had been killed.
The al-Nusra Front, a jihadist group affiliated with al-Qaeda, is one of the more powerful rebel groups battling to overthrow President Bashar al-Assad.
Al-Nusra was designated a "terrorist" organization by the United States late last year.
