HAARETZ — U.S. President Donald Trump on Tuesday agreed to a two-week ceasefire with Iran, less than two hours before his deadline for Tehran to reopen the Strait of Hormuz or face devastating attacks on its civilian infrastructure.

Trump’s announcement on social media represented an abrupt turnaround from earlier in the day, when he issued an extraordinary warning that a “whole civilization will die tonight” if his demands were not met.

Pakistan Prime Minister Shehbaz Sharif, who helped mediate the cease-fire, said in a post on X that he had invited Iranian and U.S. delegations to meet in Islamabad on Friday.

An Israeli source told Haaretz that Israel will honor the cease-fire deal but added that Jerusalem remains concerned over a possible deal and would like to have achieved more of the war’s goals before any truce comes into effect.

Sharif also said that the cease-fire extends to “everywhere including Lebanon and elsewhere, EFFECTIVE IMMEDIATELY.”

In its first official response to the cease-fire, however, Israeli Prime Minister Benjamin Netanyahu’s Office said in a statement early Wednesday local time that while Israel supports the move, the deal “does not include Lebanon.”

Trump said the last-minute deal was subject to Iran’s agreement to pause its blockade of oil and gas supplies through the strait, which typically handles about one-fifth of global oil shipments. Iran’s foreign minister, Abbas Araghchi, said in a statement that Tehran would stop counter-attacks and provide safe passage through the waterway.

“This will be a double sided CEASEFIRE!” Trump wrote on his Truth Social platform. “The reason for doing so is that we have already met and exceeded all Military objectives, and are very far along with a definitive Agreement concerning Longterm PEACE with Iran, and PEACE in the Middle East.”

Iran’s Supreme National Security Council portrayed the deal as a victory over the U.S., claiming Trump had accepted Iran’s conditions for ending hostilities.

In response, White House press secretary Karoline Leavitt said, “The truth is that President Trump and our powerful military got Iran to agree to reopening the Strait of Hormuz, and negotiations will continue.”

The war, now in its sixth week, has claimed more than 5,000 lives in nearly a dozen countries, including more than 1,600 civilians in Iran, according to tallies from government sources and human rights groups.

Two White House officials confirmed that Israel has also agreed to the two-week cease-fire and to suspend its bombing campaign on Iran. 

It was not immediately clear how soon the cease-fire would take full effect. Israeli media reported it would begin once Iran reopened the strait and that Israel expected Iranian attacks to continue in the interim.

More than an hour after Trump’s announcement, the Israeli military said it had identified missiles launched from Iran, and explosions from intercepted missiles could be heard in Tel Aviv. Gulf countries including Kuwait, Bahrain, Saudi Arabia and the United Arab Emirates also issued near-simultaneous alerts and activated air defenses.

Following these attacks, CNN reported that Iran’s supreme leader instructed all military units to stop firing, citing a statement read out on state-run news channel IRIB.

“This is not the end of the war but all military branches should follow the Supreme Leader order and cease their fire,” according to the statement.
