U.S. President Donald Trump told Israel on Tuesday "do not drop those bombs" on Iran, saying that this would be a "major violation" of the ceasefire.

"ISRAEL. DO NOT DROP THOSE BOMBS. IF YOU DO, IT IS A MAJOR VIOLATION. BRING YOUR PILOTS HOME, NOW!" Trump wrote in a post on his Truth Social platform.

Israel said on Tuesday it had identified missiles from Iran, shortly after the Israeli authorities said they had accepted a ceasefire proposed by Trump.

Iran had rejected reports of having launched missiles towards Israel following the ceasefire declared between the two sides earlier in the day, the semi-official Tasnim news agency reported.

Israeli Defense Minister Israel Katz said in a statement that he had "instructed the military to respond forcefully to Iran's violation of the ceasefire with intense strikes" against targets "in the heart of Tehran."

The missiles triggered air raid sirens across the Haifa area before being intercepted by the Israeli air defense systems, the military said. No injuries or damage had been reported.

Meanwhile, the Israeli Air Force continued its strikes in Iran, unleashing another wave of strikes in western Iran, with the military saying they had targeted missile launchers.

The latest escalation came shortly after Israeli Prime Minister Benjamin Netanyahu said Tuesday that Israel had accepted a ceasefire proposed by Trump and had achieved its war goals against Iran.

Trump had earlier announced that a ceasefire between the two sides would begin around 0400 GMT, with Iran expected to halt its operations first.

Iranian Foreign Minister Abbas Araqchi said earlier that there was no "agreement" on a ceasefire between Iran and Israel. However, he suggested Iran would be prepared to halt further retaliation if Israeli attacks stopped by 4 a.m. Tehran time (0030 GMT).

"If Israel stops its illegal aggression against the Iranian people no later than 4 a.m., Iran has no intention of continuing its response afterwards," Araqchi wrote in a post on X, adding that "the final decision on the cessation of our military operations will be made later."

The conflicting narratives raised questions about the implementation and durability of any potential ceasefire. It remained unclear whether the reported deal had been communicated through diplomatic channels, or whether either side intended to follow the terms.

Trump announced Monday evening that Israel and Iran have reached a formal agreement to implement a complete and total ceasefire, marking what he called the end of the "12-Day War."

In a post on his Truth Social platform Monday, Trump said the ceasefire would initially last 12 hours, during which the opposing sides would maintain a posture of "peace and respect."
