DUBAI, United Arab Emirates — U.S. President Donald Trump said that Israel and Iran had agreed to a “complete and total ceasefire” soon after Iran launched a limited missile attack Monday on a U.S. military base in Qatar, retaliating for the American bombing of its nuclear sites.

Iran’s foreign minister said that as long as Israel stopped its attacks by 4 a.m. local Tehran time Tuesday, Iran would halt its own. But Israel’s military warned its public Tuesday that Iran had launched missiles towards it near an hour after that time.

Sirens sounded in areas of Israel ahead of the missile barrage’s arrival.

It’s unclear what the detected missile launch would do for the ceasefire’s timeline.

Israel did not immediately acknowledge any ceasefire, but there were no reports of Israeli strikes in Iran after 4 a.m. local. Heavy Israeli strikes continued in Tehran and other cities until shortly before that time. Israel in other conflicts has stepped up its strikes just before ceasefires took effect.

“As of now, there is NO ‘agreement’ on any ceasefire or cessation of military operations,” Iranian Foreign Minister Abbas Araghchi wrote in a post on X. “However, provided that the Israeli regime stops its illegal aggression against the Iranian people no later than 4 a.m. Tehran time, we have no intention to continue our response afterwards.”

His message was posted at 4:16 a.m. Tehran time. Araghchi added: “The final decision on the cessation of our military operations will be made later.”

Trump posted on Truth Social that the 24-hour phased-in ceasefire would begin about midnight Tuesday Eastern time. He said it would bring an “Official END” to the war.

The Israeli military declined to comment on Trump’s statement and the office of Israeli Prime Minister Benjamin Netanyahu did not immediately respond to a message seeking comment.

Trump went so far as to give the conflict between Israel and Iran the name of the “12 Day War.” That recalls the 1967 Mideast war, known by some as the “Six Day War,” in which Israel fought a group of Arab countries including Egypt, Jordan and Syria.

Trump’s reference carries emotional weight for the Arab world, particularly Palestinians. In the 1967 war, Israel captured the West Bank and east Jerusalem from Jordan, the Gaza Strip and the Sinai Peninsula from Egypt, and the Golan Heights from Syria. Though Israel later gave the Sinai back to Egypt, it still holds the other territories.

Iran attack against US base

Iran’s attack Monday indicated it was prepared to step back from escalating tensions in the volatile region. The U.S. was warned by Iran in advance, and there were no casualties, said Trump, who dismissed the attack as a “very weak response.”

Qatar condemned the attack on Al Udeid Air Base as “a flagrant violation” of its sovereignty, airspace and international law. Qatar said it intercepted all but one missile, though it was not clear if that missile caused any damage.

Iran said the volley matched the number of bombs dropped by the United States on Iranian nuclear sites over the weekend. Iran also said it targeted the base because it was outside of populated areas.

Those comments, made immediately after the attack, suggested Iran wanted to de-escalate with the United States, something Trump himself said after the strikes early Sunday on Iran.

Qatar Maj. Gen. Shayeq Al Hajri said 19 missiles were fired at the base that is home to the Combined Air Operations Center, which provides command and control of air power across the region, as well as the 379th Air Expeditionary Wing, the largest such wing in the world. Trump said 14 missiles were fired, 13 were knocked down and one was “set free” because it posed no threat.

Iran announced the attack on state television, with a caption calling it “a mighty and successful response” to “America’s aggression.”

Just before the explosions, Iranian President Masoud Pezeshkian wrote on the social platform X: “We neither initiated the war nor seeking it. But we will not leave invasion to the great Iran without answer.”

Earlier reports that a missile was launched at a base housing American forces in Iraq were a false alarm, a senior U.S. military official said. The official, who spoke on condition of anonymity because he was not authorized to comment publicly, said debris from a malfunctioning Iranian missile targeting Israel had triggered an alert of an impending attack on the Ain al-Assad base.

By early Tuesday, Qatar Airways had resumed its flights after Qatar shut down its airspace over the Iranian attack on Al Udeid Air Base. Flight-tracking data showed commercial aircraft again flying in Qatari airspace, signaling Doha believed the threat on the energy-rich nation had passed.

Israel hones in on symbolic targets

Israel and Iran traded airstrikes early Tuesday morning.

Iran struck Israel with a barrage of missiles and drones while Israel said it attacked “regime targets and government repression bodies in the heart of Tehran.”

Earlier, Israel’s military put out a warning that District 6 in Tehran could be struck, while Iran, mirroring the language and maps of the Israeli military, warned people in Ramat Gan it would target “military infrastructure” there.

But Israeli officials insisted they did not seek the overthrow of Iran’s government, their archenemy since the country’s 1979 Islamic Revolution.

The latest strikes unfolded only hours after Trump himself mentioned the possibility of regime change a day after inserting America into the war with its stealth-bomber strike on three Iranian nuclear sites.
