Syria has claimed Israel represents a "grave and serious threat" at a meeting of the International Atomic Energy Agency.
The accusation, about Israel's nuclear capabilities, was made by Syrian delegate Bassam al-Sabbagh.
But according to another delegate present, comments made by other Arab nations were less hostile towards Israel than on previous occasions.
Iran, which earlier this month was accused of conducting secret research and development of nuclear weapons by the IAEA, boycotted Monday's meeting.
