Iran's supreme leader lashed out at Western countries as he led Friday prayers in Tehran for the first time in eight years, dismissing “American clowns” who he said pretend to support the Iranian nation but want to stick their "poisoned dagger” into its back. Ayatollah Ali Khamenei used his rare appearance at the weekly prayers to deliver a fiery address in which he insisted Iran would not bow to U.S. pressure after months of crushing sanctions and a series of recent crises — from the American killing of a top Iranian general to Iran's accidental shootdown of a Ukrainian passenger plane. Khamenei said the mass funerals for Gen. Qassem Soleimani, who was killed in a U.S. airstrike earlier this month, show that the Iranian people support the Islamic Republic despite its recent trials.
