Beirut - Iranian speaker of parliament Ali Larijani is to travel to Iraq and Lebanon in the next few days, according to a report published by the Saudi Arabian daily Al-Watan on Wednesday.

Larijani will convey messages from Iraqi Ayatollah Ali Sistani to Hezbollah Secretary General Sheikh Hassan Nasrallah, the daily quoted unnamed sources from Iran as saying.

The sources said that the letter carried by Larijani, who is currently visiting Manama, revealed Sistani's position on the security agreement between Iraq and the United States.

The report on the visit coincided with one published by the Iraqi Web site Almalaf on Wednesday that Nasrallah was poisoned last week and that his life was saved by Iranian doctors who were rushed to Lebanon to treat him.

The website quoted diplomatic sources in Beirut as saying that a particularly poisonous chemical substance was used against the Shi'ite militia leader.

His medical condition was apparently critical for a number of days, until the Iranian doctors arrived and managed to save his life.

A source at the Hezbollah press office described the report "as fabricated and untrue." (dpa)
