President Donald Trump sharply criticized Prime Minister Benjamin Netanyahu over Israel’s strike on Hezbollah targets in Beirut, saying the operation should not have happened and claiming it delayed the expected signing of a U.S.-Iran agreement.

Speaking to Channel 12 in comments reported by Barak Ravid, Trump said he was furious after being told Israel was striking Beirut shortly before the deal was supposed to be signed. “They called me and said, ‘Sir, Israel is attacking Beirut’ an hour before we were supposed to sign the agreement. I couldn’t believe it was happening. It’s very bad,” Trump said.

Trump also criticized Netanyahu personally over the decision. “Why did Bibi carry out this attack? Hezbollah fired and hit the middle of nowhere. Nobody was hurt. Then he had to carry out that **** attack, and in Beirut of all places. It really angered me,” he said. “Bibi has no **** judgment. I passed that message to him. I’m very unhappy.”

Trump later confirmed the confrontation to Fox News, saying he called Netanyahu and asked him, “What the heck are you doing?” According to Israeli reports, Trump also said he would ask Iran not to respond with ballistic missile fire, as Washington tried to keep the confrontation from derailing the diplomatic process.

Trump defended the proposed agreement, saying it would be good for Israel because it would prevent Iran from obtaining a nuclear weapon, allow inspections of suspicious sites in Iran with 24 hours’ notice, and eliminate Iran’s enriched uranium stockpile.

Trump said the strike came just before the agreement was expected to be finalized. “We were supposed to sign the agreement this morning and the Israeli strike in Beirut delayed it,” he said. “I think the signing will still happen today in a few hours. But the Israeli strike shook things up.”
