Iran’s supreme leader Ali Khamenei on Saturday accused US President Donald Trump of being responsible for “casualties” during a protest wave in the country that rights groups said was met with a deadly crackdown.“We hold the American president guilty for the casualties, damages and accusations he has levelled against the Iranian nation,” he told a crowd of supporters during an address marking a religious holiday.“This was an American conspiracy,” he said, adding that “America’s goal is to swallow Iran... the goal is to put Iran back under military, political and economic domination.”Developing
