Akhtari recently took up the post of Iranian ambassador to Damascus for the second time. From 1989 to 1998, while he was ambassador, the hard-line cleric was behind a number of attacks in the region orchestrated by Iranian intelligence and carried out by Irans proxies.
Irans official media have been pouring scorn on Syrias former vice-president, Abdel-Halim Khaddam, calling him a traitor and a tool in the hands of the Global Oppressor, a reference to the United States.
Akhtari heads the World Assembly of Ahl-Bait, a government-run body that has an active recruitment drive targeting Muslims in other countries.
In 1996, during his first tenure as the top Iranian envoy to Damascus,
Akhtari said, Tehran has obtained Muslim soldiers all over the world to bring the United States and Israel to their knees. He described then U.S. President Bill Clinton and Americas allies as slaves of Israel whose time had reached an end.
Islam will soon come and get you. Our soldiers have been sent to all the hills and corners of the world and they are ready to carry out martyrdom-seeking attacks everywhere, Akhtari said.
Between 1998 and his reappointment as Irans ambassador to Syria, Akhtari worked in the office of Supreme Leader Ayatollah Ali Khamenei and was his principal Arab affairs adviser.
Earlier this week, Syrian leader Bashar al-Assad defended Tehran in its legitimate right to carry out its nuclear activities.
In a meeting with Irans Deputy Foreign Minister Mohammad-Reza Baqeri in Damascus, al-Assad described Israel as a regional threat.
The Syrian leader said that the Jewish state was a threat to both regional and global peace with its huge atomic weapons arsenal.
He also underlined the importance of Tehran-Damascus bilateral relations, and invited Iranian President Mahmoud Ahmadinejad to visit Damascus.
Irans state-run news agency reported on Saturday that Syria was setting up Persian language centres in three of its universities.
