Ayatollah Ali Khamenei, the supreme leader of Iran, warned in a post to X on Wednesday that a U.S. attack on Iran in support of Israel "without a doubt will cause irreparable damage."

Israel said it had struck uranium enrichment sites in Iran after the two countries launched another barrage of missiles at each other overnight.

Signs continued to emerge that the United States was considering joining Israel’s bombing campaign. Israel carried out strikes on Tehran overnight after Iran fired two new rounds of missiles.
