Iran’s supreme leader Ayatollah Ali Khamenei wants protesters to rise up across the U.S. and Europe and challenge the renewed Israeli military campaign in Gaza. The Times of Israel reports Khamenei made his call for action in a speech designed to rally anti-Israel activists everywhere, “to strongly oppose this treacherous, horrendous act.” “Once again children are being killed, homes are being destroyed, and civilians are being displaced. The people must stop this tragedy,” Khamenei says in a Nowruz address, according to an English transcript posted on his website.
