Trump says 'shooting' will resume if Iran fails to uphold ceasefire

Deal's fractures emerged quickly as Israel carried out its heaviest strikes on Beirut

US President Donald Trump said on Wednesday its military ships and aircraft will remain around Iran and threatened that the US will start "shooting" again unless Tehran fully complies with the deal reached with Washington.

"All US Ships, Aircraft, and Military Personnel, with additional Ammunition, Weaponry ... will remain in place in, and around, Iran, until such time as the REAL AGREEMENT reached is fully complied with," Trump said on his Truth Social platform.

"If for any reason it is not, which is highly unlikely, then the "Shootin’ Starts," bigger, and better, and stronger than anyone has ever seen before," the president added.

Iran had said earlier on Wednesday that it would be "unreasonable" to proceed with talks to forge a permanent peace deal with the United States after Israel pounded Lebanon with its heaviest strikes yet on Wednesday, killing hundreds of people.

The two sides appeared to be far apart on Iran's nuclear program, with Trump saying Iran had agreed to stop enriching uranium, and Iran's parliament speaker, Mohammed Bager Qalibaf, saying it was allowed to continue enriching uranium under the terms of the ceasefire.

"It was agreed, a long time ago, and despite all of the fake rhetoric to the contrary - NO NUCLEAR WEAPONS and, the Strait of Hormuz WILL BE OPEN & SAFE," Trump added in his late Wednesday's Truth Social post.

Iran and the US announced a two-week truce on Tuesday aimed at paving the way for a final agreement to end the war launched by the United States and Israel against Iran on Feb. 28, which has left many dead and wounded.

The announcement came less than two hours before the expiration of a deadline that Trump had repeatedly extended for Iran to reopen the Strait of Hormuz and accept an agreement or face “the destruction of an entire civilisation.”

Lebanon

The deal's fractures emerged quickly as Israel carried out the heaviest strikes on its neighbour -- including in densely packed central Beirut, since the Iran-backed militant group Hezbollah joined the war in early March.

At least 182 people were killed and nearly 900 wounded on Wednesday, the Lebanese Health Ministry said.

Amnesty International’s regional director for the Middle East and North Africa, Heba Morayef, says that the “nightmare for civilians has become more terrifying” in Lebanon, “just hours after the world cautiously welcomed news of a US-Israeli ceasefire with Iran”.

“Civilians in Lebanon are already paying an unbearable price with children, health workers and journalists amongst those killed – the latest attacks will only escalate this devastating human toll,” Heba said.

Israel said its battle against Hezbollah was not part of the US-Iran truce agreed late Tuesday, an argument echoed by US Vice President JD Vance, days before he is due to lead talks with Tehran in Pakistan.

"If Iran wants to let this negotiation fall apart... over Lebanon, which has nothing to do with them, and which the United States never once said was part of the ceasefire, that's ultimately their choice," he said.

But Iran's parliament speaker Mohammad Bagher Ghalibaf appeared to threaten the ceasefire, posting on X that the "workable basis on which to negotiate" had already been violated, making further talks "unreasonable".

Adding to the fragility of the truce, agreed hours before a deadline set by US President Donald Trump, a senior US official said Iran's 10-point plan was not the same set of conditions the White House had agreed to in order to pause the war.

In Lebanon, where UN rights chief Volker Turk called the scale of killing "horrific", strikes across the capital, Beirut, without warning triggered scenes of horror and panic.

More than 1,700 people have been killed in Lebanon since Israel launched airstrikes and a ground invasion last month, local officials said.
