Iran live updates: Trump says 'no more Mr. Nice Guy' if Iran refuses nuclear deal

Three members of Lebanon's Civil Defense were killed by Israeli strikes in southern Lebanon on Tuesday while trying to carry out a rescue operation, Lebanon's Civil Defense said.

Hussein Sati, Hadi Daher and Hussein Ghadbouni were all long-time volunteers with the Civil Defense, the service said. Sati is survived by two children, while Daher and Ghadbouni were both in their 20s.

The Lebanese Armed Forces said two of its soldiers were also injured in the same attack.

President Donald Trump posted to social media early on Wednesday morning warning of fresh consequences if Tehran does not agree to a new nuclear deal.

"Iran can't get their act together. They don't know how to sign a nonnuclear deal. They better get smart soon!" Trump wrote, adding, "No more Mr. Nice Guy!"

President Donald Trump on Tuesday issued an apparent rebuke of German Chancellor Friedrich Merz's criticism of American strategy in Iran, saying that the German leader doesn't "know what he's talking about."

Merz, Trump claimed, "thinks it's OK for Iran to have a Nuclear Weapon" -- something Merz did not say in his Monday criticism of the U.S.-Israel campaign.

"If Iran had a Nuclear Weapon, the whole World would be held hostage. I am doing something with Iran, right now, that other Nations, or Presidents, should have done long ago," Trump said.

"No wonder Germany is doing so poorly, both Economically, and otherwise," Trump added in the post.

Merz said at an event on Monday that the U.S. had "no strategy" in Iran and was "being humiliated by the Iranian state leadership."

The Israel Defense Forces said in a post to X on Wednesday that its strikes against alleged Hezbollah targets in southern Lebanon continued through Tuesday.

Israeli operations were ongoing "north of the forward defense line," the IDF said, referring to a line inside southern Lebanon to which Israeli forces are advancing, which is intended as the forward boundary of a planned "buffer zone" along the Israeli-Lebanese border.

The IDF also said there were "several incidents" of drone attacks on Israeli forces operating in southern Lebanon on Tuesday, in which one soldier was "lightly wounded."
