Iranian President Mahmoud Ahmadinejad told his Syrian counterpart, Bashar Assad, on Friday that Israel and the US were "weakening with God's help".
During the phone conversation quoted by Iranian news agencies Ahmadinejad said, "The strong camp of friendly countries such as Iran and Syria are on their way to victory."
According to the Iranian leader, "The regional conditions are working in favor of the Muslim countries and against the Zionist regime and its allies."
Assad said that Syria and Iran were "in the same fortress", and Ahmadinejad said the two countries should "take advantage of abilities and opportunities in a wise manner".
Early in March Iran's president convened a conference for the support of the Palestinian people, in which he said legal measures would bear results "and the criminals of the Zionist regime will eventually be put to death".
He called for "a global front against Zionism which would work to support the people in Gaza and in Palestine on the one hand, and work to punish the Zionist criminals on the other hand."
Syrian Foreign Minister Walid al-Muallem said earlier this month that his country's relationship with Iran would remain intimate. He told Arab League Secretary-General Amr Moussa that relations with the country were "excellent".
