DUBAI (AlArabiya.net) - Rumors that an assassination attempt was made on Hezbollah leader Hassan Nasralleh circulated in the Arab and Israeli media despite an official denial by the opposition group Thursday.

According to a state-affiliated Iraqi website, Hassan Nasrallah was poisoned with a highly toxic chemical and would have died without the intervention of Iranian doctors, the U.A.E. newspaper al-Bayan reported Thursday.

Hezbollah refused to comment on the rumors and Hezbollah’s media outlets did not mention the alleged assassination attempt.

A Hezbollah-affiliated website said the Iraqi website that initially reported the rumors is related to an Arab intelligence service, though it did not specify which country.

Diplomatic sources in Beirut said Nasrallah was in critical condition after being poisoned whenan Iranian medical team of 15 doctors flew to Beirut on a fully equipped plane and saved his life, according the Iraqi website. The sources added that Nasrallah was still suffering from the after-effects of the poison.

According to media reports, three days ago there was unusual activity at the Rafik Hariri International Airport when the doctors arrived on Russian-made Antonov 74 military aircraft. There was tight security on the way from the airport to the Southern district of Beirut, where Nasrallah reportedly lives.

Western diplomatic sources commented on the rumors, saying that Israel was most likely behind the plot.

The sources added that the poisoning might have been through food or touching and that chemicals like organic phosphorus or chlorophenol could have been used. A toxic chemical like sodium peroxide or sodium oxide might have also been sprayed in his bedroom or places where he spends a lot of time.

A senior Hezbollah official called the rumors "fabrications" and said, "I haven't seen him in a week, but I know he's in good health."
