Iran's powerful Revolutionary Guards said on Wednesday that the Washington's long-awaited Israeli-Palestinian peace plan was doomed to failure and said the Palestinian resistance movement will firmly respond to those who proposed such deal.
U.S. President Trump has touted the plan as the "deal of the century" but Palestinian officials have already spurned the U.S. effort, which they believe will be heavily biased in favour of Israel.
Trump's team, headed by his Middle East adviser and son-in-law Jared Kushner, is set to unveil the plan at an international investment conference in Bahrain in late June.
Iran's Revolutionary Guards said in a statement carried by Tasnim news agency that the only solution to the Israeli-Palestinian conflict was "withdrawal of Zionists from the occupied lands, and return of Palestinian refugees to hold free elections".
Any other plan will fail, the statement said, adding that "fighters in the Islamic Resistance Movement of Palestine will firmly respond to those who proposed the deal of the century and traitors who are trying to normalise ties with Zionist regime".
Opposition to Israel is a touchstone of belief for Shi'ite-led Iran, which backs Palestinian and Lebanese Islamist militant groups opposed to peace with Israel, which Tehran refuses to recognise.
President Hassan Rouhani said in remarks carried by the state television on Wednesday that "The deal of the century would in reality be a bankruptcy of the century for those who proposed it."
Israel, the United States and its chief Sunni Arab ally Saudi Arabia accuse Iran of fomenting tension in the Middle East and of sponsoring terrorism. This is denied by Tehran.
Iranian Foreign Minister Mohammad Javad Zarif tweeted: "Al-Quds (Jerusalem) is neither America's to give away nor Israel's to take. And NOT for brutal accomplices to try to buy."
