Trump announced on his social media platform that Israel and Iran have agreed to a "Complete and Total CEASEFIRE" that will begin around midnight Tuesday.

Representatives for Israel and Iran did not immediately appear to confirm the agreement.

Read Trump's full Truth Social post:

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! 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!

Iran's leader, Ayatollah Ali Khamenei, issued a defiant-sounding statement shortly after Trump celebrated the bloodless outcome of Tehran's retaliatory strike on a U.S. military base in Qatar.

"Those who know the Iranian people and their history know that the Iranian nation isn't a nation that surrenders," Khamenei wrote on X.

The post conveyed a marked contrast in tone from Trump's latest social media message, an all-caps declaration suggesting that the latest developments in the Middle East have established world peace.

The U.S. Embassy in Sweden is warning Americans to "exercise increased caution," because Iran "may be pressuring local criminal gangs, including the Foxtrot Network, to carry out attacks in Sweden against U.S. and Israeli interests."

The embassy encourages Americans living in Sweden to "maintain awareness of their surroundings, particularly near the U.S. Embassy," per an advisory.

The Foxtrot Network is a gang in Sweden and "prominent drug trafficking organization," according to the State Department, which sanctioned the group in March.

The State Department said at the time that Iran had "leveraged the Foxtrot Network to carry out attacks on Israeli and Jewish targets in Europe, including the Israeli Embassy in Stockholm, Sweden, in January 2024."

Iranian leader Ayatollah Ali Khamenei says that his country "will not submit to anyone's harassment" after Iran launched retaliatory missiles at U.S. bases in the Middle East.

"We didn't harm anyone," Khamenei said on X, according to a Google translation.

"And we will not accept any harassment from anyone under any circumstances. And we will not submit to anyone's harassment," he wrote.

"This is the logic of the Iranian nation."

There are approximately 45,000 American service members stationed in the Middle East, according to a recent Reuters analysis.

This number is in constant flux, however, and it reflects estimates of personnel at several bases where troop numbers are not publicly acknowledged, due to national security concerns.

The United States' Al Udeid Airbase in Qatar is the biggest American base in the region, with around 10,000 servicemembers stationed there.

Iraq hosts the Al Asad air base, where another 2,500 Americans are posted.

In Bahrain, home to the U.S. Navy's 5th Fleet, around 9,000 seamen are stationed at any given time.

South of Abu Dhabi in the United Arab Emirates is the Al Dhafra Airbase, which is shared between the United States and the UAE Air Force.

Saudi Arabia hosts both American soldiers and large-scale U.S. missile batteries at Prince Sultan Air Base, south of the capital Riyadh. U.S. soldiers in Saudi Arabia numbered 2,321 in 2024, according to a letter released by the White House.

The Muwaffaq al Salti Air Base in Jordan hosts the U.S. Air Force Central's 332nd Air Expeditionary Wing, according to a 2024 congressional report cited by Reuters.

Trump said Iran gave the U.S. "early notice" of its missile attack on an American military base in Qatar, "which made it possible for no lives to be lost, and nobody to be injured."

Trump thanked Iran for that heads up, but nevertheless called the retaliatory strike a "very weak response" that was "very effectively countered" by the U.S.

"Most importantly, they've gotten it all out of their "system," and there will, hopefully, be no further HATE," Trump wrote on Truth Social.

Dubai airports have resumed "full operations" following a brief pause following the attack, per a statement.

"While Dubai Airports works with airlines to ensure flights operate according to approved schedules, some flights may experience delays or cancellations," the statement from the Dubai Media Office said.

Republican House Speaker Mike Johnson said that "this is the retaliation that was expected," after Iran said it launched missile strikes on U.S. military bases in Qatar and Iraq.

"So far, so good, no casualties, so far as we know," he told reporters.

He also said that it is not an "appropriate time" for a war powers resolution, and he doesn't think it's "necessary."

"Listen, for 80 years, presidents of both parties have acted with the same commander in chief authority under Article II," Johnson said, referring to the article that designates the president as "commander in chief" of the military.

Johnson said that he received a classified briefing Monday morning on the conflict with Iran.

"I know that the national security team is in the Situation Room, even as we speak, and they're monitoring this," he said.

U.S. crude oil futures sold off steeply, on hopes the Middle East conflict will de-escalate after Iran's retaliatory strike on a U.S. base left no reported casualties.

U.S. West Texas Intermediate fell $5.33, or 7.22%, to close at $68.51 per barrel, while global benchmark Brent shed $5.53, or 7.18%, to settle at $71.48 per barrel.

The oil market appears to have avoided its worst-case scenario, for now, in which Iran attempts to close the Strait of Hormuz. Some 20 million barrels per day of crude, or 20% of global consumption, flowed through the strait in 2024, according to the Energy Information Administration.

U.S. crude has given up most of its gains since Israel started bombing Iran on June 13. Brent is up more than 2% since the conflict began.

The United Arab Emirates "has condemned in the strongest terms," the attack on the Al Udeid Air Base, per a statement from the Ministry of Foreign Affairs.

"The UAE underscored its categorical rejection of any attack that threatens the security and safety of the State of Qatar, stressing that such actions undermine regional security and stability," the statement said.

The UAE also fully supports any measures by Qatar "aimed at safeguarding the security and safety of its citizens and residents."

"The UAE reaffirmed the urgent need to halt military escalation, and warned against continued acts of provocation that threaten to destabilize regional security and risk dragging the region into dangerous paths with catastrophic repercussions for international peace and security," the statement said.

Saudi Arabia condemned and denounced the attack "in the strongest terms possible," according to a statement from the Ministry of Foreign Affairs.

The attacks constitute "a flagrant violation of international law and the principles of good neighborliness, and an entirely unacceptable act that cannot be justified under any circumstances," per the statement.

"The Kingdom affirms its full solidarity with and unwavering support for the State of Qatar and places all its capabilities at Qatar's disposal in support of any measures it may take," the statement continues.

— Erin Doherty

Abdullah Almulla, who was in Doha during the attack, described hearing "bangs in the sky," while he was on his way home from work, during an interview on CNBC's 'The Exchange.'

He said that he did not have any indication that any of the strikes impacted any residential or urban areas in Doha.

"It is scary, it's not something I ever heard in my life or ever experienced, so ... it's a bit worrisome, I'm worried for my friends and family and I just want them to be safe," said Almulla, who is from Qatar and works with Qatar News Agency.

He said that his friends and family appear to be safe from the attack.

Iran gave Qatar advanced notice that it was launching an attack on the U.S. base near Doha, three Iranian officials familiar with the plans told The New York Times.

Iran's retaliatory strike was meant to be symbolic, while leaving an exit ramp open for all sides, the Times reported.

In its statement confirming the attack on the Al Udeid Air Base, Iran's national security council said its action "posed no threat whatsoever to our friendly and brotherly nation, Qatar, or its honorable people."

Qatar has condemned the strike.

Amid escalating nuclear tensions between the U.S. and Iran, President Donald Trump posted on Truth Social praising the U.S.'s Saturday attacks on nuclear sites in the Middle Eastern country.

"The sites that we hit in Iran were totally destroyed, and everyone knows it," he wrote.

Trump blamed "the Fake News" for allegedly trying to "demean" the impact of the sites that were hit, calling out "NBC Fake News" by name.

"It never ends with the sleazebags in the Media, and that's why their Ratings are at an ALL TIME LOW — ZERO CREDIBILITY!" he added.

Iran claims that the number of missiles used in the operation was the same as the number of bombs the United States used in its strike on Iran over the weekend, CNBC's Megan Cassella reports, based on a statement from Iran's Supreme National Security Council.

The base was located away from urban infrastructure and residential areas in Qatar, the statement said.

Kuwait Airways is suspending all departing flights from the country due to regional tensions until further notice, the airline posted on X.

The suspension will remain in effect "until further notice."

EgyptAir announced in a social media post that all Egypt flights to and from cities in the Persian Gulf have also been canceled "until the situation stabilizes in the region."

The flight suspensions follow Qatar closing its airspace to commercial flights just before Iran launched missiles attacking the U.S. base in Qatar. Bahrain also temporarily suspended air traffic, according to NBC News.

Iran did not move nuclear material out of its Fordo facility before the U.S. strike on Saturday, Sen. Markwayne Mullin told CNBC's "Squawk Box" Monday morning, citing U.S. intelligence.

A New York Times report published Sunday cited two unnamed Israeli officials who said Iran appeared to have moved nuclear material and equipment from Fordo before the U.S. bombed three Iranian nuclear sites.

"Our intelligence report says they didn't," the Republican senator said.

"In fact, we actually believe they stored more of it in Fordo because they believe Fordo was impenetrable," Mullin said. "They thought it was a safe place to be."

Airlines diverted more flights in the Middle East as Qatar's airspace closed and areas above other Persian Gulf nations were reportedly also off limits after Iran said it attacked a U.S. military base in Qatar.

At least six commercial aircraft turned around near the United Arab Emirates' airspace, according to flight-tracking platform Flightradar24, which also reported that the UAE airspace was closed.

Several major international airlines have also scaled back service to major hubs like Doha, Qatar, and Dubai in the United Arab Emirates, or have offered travelers vouchers to travel at a later date because of the conflict.

Qatar "strongly condemns" the attack at the Al-Udeid air base and considers it "a flagrant violation of the sovereignty of the State of Qatar, its airspace, international law and the United Nations Charter," Majed Al Ansari, the official spokesperson for Qatar's Ministry of Foreign Affairs, wrote on X.

"We reassure that Qatar's air defenses successfully thwarted the attack and intercepted the Iranian missiles," he wrote.

He said that the base had been evacuated prior to the attack, "given the tensions in the region."

"We confirm that no injuries or human casualties resulted from the attack," he continued.

"We affirm that Qatar reserves the right to respond directly in a manner equivalent with the nature and scale of this brazen aggression, in line with international law," he said.

Stock indexes are positive so far this afternoon despite the Iranian attacks on U.S. bases, as investors view the missile fire as a relatively limited response to the U.S. bombing of Iran's nuclear facilities.

The alternative, and a much more costly scenario for traders, would have been if Iran had targeted oil tankers in the Strait of Hormuz, for example, or Gulf state oil production sites.

Oil prices also fell this afternoon after briefly jumping, moved lower by the same working assumptions about Iran's retaliation.
