U.S. President Donald Trump's plan for peace in the Middle East is doomed to failure, the Supreme Leader Ayatollah Ali Khamenei told Iranian state television on Wednesday.
"This deal of the century will die before Trump does," Khamenei said, adding that the plan was "stupid but also insidious."
Khamenei called on Palestinians and the whole Muslim community, to oppose the plan, and said Iran will support Palestinian armed groups as much as it can.
"We believe that Palestinian armed organizations will stand and continue resistance and the Islamic Republic sees supporting Palestinian groups as its duty," Ayatollah Ali Khamenei said in a speech carried on his website.
"So it will support them however it can and as much as it can and this support is the desire of the Islamic system and the Iranian nation."
The Iranian leader also added that Palestinians should respond with "bold resistance," and to "force out the zionist enemy and the U.S. through Jihad."
He said the only solution for the conflict in the Middle East was a referendum asking all Palestinians to decide themselves on a political solution for their country.
Following a rejection of the plan by Palestinian officials even before it was formally released, Iran's leaders also strongly condemned it in strong terms. President Hassan Rowhani called it "despicable" and unacceptable for the whole region.
Foreign Minister Mohammad Javad Zarif called the plan the "dream project of a bankruptcy-ridden real-estate developer" and a nightmare for the whole region and the world.
Trump recently presented a proposal to address the bitter decades-long conflict at the core of tensions across the Middle East.
His plan would give Israel control over Jewish settlements on the West Bank and the strategic Jordan Valley, while also calling for the creation of a Palestinian state. It differs significantly from the 1967 borders that have previously been the basis for peace plans.
Khamenie also said that Arab leaders who support Trump's peace plan are incompetent, according to a tweet on his official account.
"Don't look at the presence of a few, #traitorous Arab heads of state for the 'Deal of the Century'. They're incompetent and have no respect among their own nation," wrote Khamenei.
