US President Donald Trump announced that the ceasefire between Iran and Israel is now officially in effect and urged all parties to fully respect and adhere to it.

Taking to his official social media account, Trump posted: "THE CEASEFIRE IS NOW IN EFFECT. PLEASE DO NOT VIOLATE IT! DONALD J. TRUMP, PRESIDENT OF THE UNITED STATES!"

Trump posted on his social media account late on Monday night that a ceasefire had been agreed upon between Israel and Iran.

"CONGRATULATIONS TO EVERYONE! It has been fully agreed by and between Israel and Iran that there will be a Complete and Total CEASEFIRE (in approximately 6 hours from now, when Israel and Iran have wound down and completed their in progress, final missions!), for 12 hours, at which point the War will be considered, ENDED!," Trump said in a post on Truth Social.

Trump claimed a 12-hour ceasefire between Israel and Iran had been reached. The ceasefire, he said, would begin in six hours.

He wrote: "Officially, Iran will start the CEASEFIRE and, upon the 12th Hour, Israel will start the CEASEFIRE and, upon the 24th Hour, an Official END to THE 12 DAY WAR will be saluted by the World. During each CEASEFIRE, the other side will remain PEACEFUL and RESPECTFUL.

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.”

This is a War that could have gone on for years, and destroyed the entire Middle East, but it didn’t, and never will! God bless Israel, God bless Iran, God bless the Middle East, God bless the United States of America, and GOD BLESS THE WORLD!"

Later, a senior Iranian official reportedly confirmed that Tehran has agreed to a US-proposed ceasefire with Israel, brokered by Qatar. However, other Iranian officials have publicly denied the existence of any such proposal.

“Iran has not received any formal ceasefire proposal,” one official stated, adding that Tehran “will continue fighting until a just and lasting peace is achieved.” The official also warned that “any such statements will be viewed as misinformation or deception, aimed at justifying further attacks on Iranian interests.”

Despite the denial, diplomatic sources say Qatar has played a key mediating role in efforts to de-escalate tensions between Iran and Israel.

Trump calls for peace in region

A couple of hours ago, Donald Trump had downplayed Iran’s ballistic missile strike on the Al Udeid Air Base in Qatar, claiming Tehran had provided early warning ahead of the attack and calling for de-escalation and peace in the region.

In a series of posts on Truth Social, Trump said no American lives were lost and damage was minimal as all 14 missiles launched by Iran were either intercepted or diverted. The missiles were aimed at the US military’s largest base in the Middle East, which also hosts Qatari forces and other allied personnel.

"I am pleased to report that NO Americans were harmed, and hardly any damage was done. Most importantly, they’ve gotten it all out of their 'system,' and there will, hopefully, be no further HATE," Trump said.

The president added that Iran's forewarning allowed for protective measures to be taken, claiming that no Qataris or Americans were killed or wounded in the strike.

“I want to thank Iran for giving us early notice, which made it possible for no lives to be lost, and nobody to be injured,” Trump wrote. "Perhaps Iran can now proceed to Peace and Harmony in the Region, and I will enthusiastically encourage Israel to do the same."

Iran attacks US base in Qatar

Iran's armed forces said in a statement that they targeted the Al-Udeid base in Qatar with a 'devastating and powerful' missile attack. They said they will not leave any attack on Iran's territory unanswered under any circumstances.

Iran's top security body said in a statement that its armed forces used the same number of bombs that the US had used in attacking Iran’s nuclear facilities. It also said the US base was far from urban facilities and residential areas in Qatar.

The Iranian Supreme National Security Council says that the missile strike against Al Udeid Air Base was away from residential areas in Qatar. “This action does not pose any threat to the friendly and brotherly country, Qatar, and its noble people, and the Islamic Republic of Iran remains committed to maintaining and continuing warm and historic relations with Qatar,” the council said in a statement.
