President Donald Trump declared Israel and Iran have agreed to a ceasefire after missile exchanges, claiming the ’12-day war’ will end following a phased implementation over 24 hours. 

“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 shared in a post on his social media platform Truth Social. 

“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,” Trump added.

Trump praised both countries for their “Stamina, Courage, and Intelligence” to end what he called “THE 12 DAY WAR.”

Rep. Marlin Stutzman, R-Ind., also shared his thoughts on the ceasefire between Israel and Iran and called it “huge.”

 “It sends a message to the greater part of the world that, this president, he will negotiate with you. He wants to find a way to do this. But if, if you’re not going to negotiate, there’s going to be consequences,” Stutzman said. 

The president’s announcement comes after Iran launched at least six missiles toward America’s Al-Udeid Air Base in Qatar on Monday, retaliating for Trump’s attack on Tehran’s nuclear program this weekend.

Qatar’s foreign ministry condemned the strike in a statement, saying the missiles were destroyed and there were no casualties.

“I’d like to thank the Highly Respected Emir of Qatar for all that he has done in seeking Peace for the Region,” Trump wrote in an earlier Monday post.

“Regarding the attack today at the American Base in Qatar, I am pleased to report that, in addition to no Americans being killed or wounded, very importantly, there have also been no Qataris killed or wounded. Thank you for your attention to this matter!’
