Iran's supreme leader Ayatollah Ali Khamenei predicted Wednesday that Donald Trump would outlive the US president's controversial proposals for Israeli-Palestinian peace. "This plan will certainly not work and it will die before Trump," Khamenei told a gathering in Tehran to mark the February 1979 Islamic revolution that toppled Iran's US-backed shah.

"The Americans negotiated with the Zionists on something that doesn't belong to them," Khamenei said in a speech aired on state television. "We believe the Palestinian militant organisations will rise up and carry on the resistance," he said, adding that Iran "considers it its duty to support Palestinian groups".
