Hezbollah leader Hassan Nasrallah was the victim of an Israeli poisoning attack and was saved by Iranian doctors who rushed to his bedside, an Iraqi Web site reported.
"High-ranking diplomatic sources" in Beirut, Lebanon, blamed Israel for the reported attack, according to Almalaf Yon.
The Shiite militant leader was in a critical condition until Iranian doctors were dispatched from Tehran to save his life, Almalaf Yon reported.
Nasrallah lives the life of a fugitive due to fears of Israeli assassination attempts, hiding out in secret locations in the Hezbollah neighborhood of Dahiya in Beirut.
He rarely appears in public and only for short periods of time.
This latest web-based rumor about Nasrallah follows another about Meir Dagan, the head of Israel's Mossad intelligence agency. Jordanian Internet sites wrongly claimed earlier this week that he had been assassinated in Jordan.
Hezbollah officials have denied that Nasrallah was the victim of a poison attack.
