US President Donald Trump said on Monday that a "complete and total" ceasefire between Israel and Iran will go into force with a view to ending the conflict between the two nations, while Iran's foreign minister said Tehran did not intend to continue its strikes if Israel stopped its attacks.
Trump appeared to suggest that Israel and Iran would have some time to complete any missions that are underway, at which point the ceasefire would begin in a staged process.
"On the assumption that everything works as it should, which it will, I would like to congratulate both Countries, Israel and Iran, on having the Stamina, Courage, and Intelligence to end, what should be called, 'THE 12 DAY WAR'," Trump wrote on his Truth Social site.
U.S. President Donald Trump hailed the Iran-Israel ceasefire as "a wonderful day for the world" and expressed optimism that the truce would last indefinitely, telling NBC News, "It’s going to go forever."
According to Reuters, citing a White House official, Israel agreed to the ceasefire on the condition that Iran refrains from further attacks, and Iran has reportedly assured the U.S. it will honor this commitment.
Behind the scenes, senior U.S. officials—including Vance, Rubio, and envoy Witkoff— reportedly conducted direct and indirect negotiations with Iranian representatives to help broker the agreement, Reuters also reported.
Despite US President Donald Trump’s announcement of a forthcoming ceasefire, Tel Aviv has yet officially commented on the agreement.
Meanwhile, Iran's foreign minister said Tuesday Tehran did not intend to continue its strikes if Israel stopped its attacks, hours after US President Donald Trump's announcement.
Abbas Araghchi suggested that Iran had already halted its operation at 4am Tehran time (0030 GMT) -- and wanted a simultaneous end in attacks from Israel as well.
"It has been fully agreed by and between Israel and Iran that there will be a Complete and Total CEASEFIRE," Trump wrote on his Truth Social platform.
"Upon the 24th hour, an official end to the 12-day war will be saluted by the world," he said, adding that both sides had agreed to remain "peaceful and respectful" during each phase of the process.
Previously, CNN reported shortly before Trump's post that Iran had not received any ceasefire proposal and saw no reason for one, citing a senior Iranian official.
However, Reuters reported early on Tuesday that Qatar's Prime Minister Sheikh Mohammed bin Abdulrahman Al Thani secured Tehran's agreement to the U.S. proposal during a call with Iranian officials, citing an official briefed on the negotiations.
The phone call came after Trump told Qatar's emir that Israel had agreed to the ceasefire and asked for Doha's help persuading Tehran to also agree to the ceasefire deal, the official said.
Earlier, Trump said he would encourage Israel to proceed towards peace after dismissing Iran's attack on an American air base that caused no injuries and thanking Tehran for the early notice.
Iran announced it had launched missiles at a US base in Qatar earlier on Monday in retaliation for American strikes on key nuclear facilities.
Qatar, which lies 190 kilometres (120 miles) south of Iran and is home to the largest US military facility in the Middle East, said its "air defences successfully intercepted a missile attack targeting Al Udeid Air Base".
Hours earlier, three Israeli officials had signaled Israel was looking to wrap up its campaign in Iran soon and had passed the message on to the United States.
S&P 500 futures rose 0.4% late on Monday, suggesting traders expect the U.S. stock market to open with gains on Tuesday.
