Saudi Arabia and the United Arab Emirates each carried out separate military strikes on Iranian soil in late March and early April, according to Western officials and regional sources, a dramatic widening of the conflict that began when the United States and Israel launched airstrikes on Iran on February 28.
The Saudi attacks, carried out by the Saudi Air Force, were assessed by two Western officials to have taken place in late March. The UAE's armed forces reportedly hit an oil refinery on Iran's Lavan Island at the start of April, an assault that caused significant damage and disabled much of the facility's production capability. Social media footage showed fire engulfing the refinery.
The strikes mark the first known direct Gulf Arab military action against Iran in the current war, and they came only after Iran had hammered all six Gulf Cooperation Council states with missiles and drones, targeted civilian airports, energy infrastructure, and population centers, and closed the Strait of Hormuz to shipping, disrupting global trade.
The broader conflict traces back to coordinated U.S. and Israeli airstrikes on Iran on February 28. Tehran responded by lashing out across the region. A Reuters tally of Saudi defence ministry statements counted more than 105 drone and missile attacks on Saudi Arabia in the single week of March 25, 31. The kingdom absorbed wave after wave of Iranian fire.
By March 19, Saudi Foreign Minister Prince Faisal bin Farhan had drawn a public line. At a press conference in Riyadh, he said the kingdom "reserved the right to take military actions if deemed necessary." Three days later, Saudi Arabia declared Iran's military attaché and four embassy staff members persona non grata.
The threat was not empty. Western officials assessed that the Saudi Air Force struck Iranian targets on Iranian soil in late March. One Western official described the action plainly:
"Tit-for-tat strikes in retaliation for when Saudi (Arabia) was hit."
The strikes were not publicized. Neither Riyadh nor Abu Dhabi announced them. A senior Saudi foreign ministry official, asked for comment, did not directly address whether strikes had been carried out. Instead, the official offered careful diplomatic language:
"We reaffirm Saudi Arabia's consistent position advocating de-escalation, self-restraint and the reduction of tensions in pursuit of the stability, security and prosperity of the region and its people."
Iran's foreign ministry did not respond to requests for comment. Neither did the White House.
The UAE's role was even more striking. At the start of April, Emirati forces reportedly struck an oil refinery on Lavan Island, a small Iranian island in the Persian Gulf. The assault disabled much of the facility's production capability. The Wall Street Journal first reported the UAE's direct combat role, and the scope of Iranian fire the Emirates absorbed helps explain why Abu Dhabi acted. Iran reportedly launched more than 2,800 missiles and drones at the UAE during the conflict, targeting airports, energy infrastructure, and population centers.
Dina Esfandiary, an analyst, told the Journal: "It's significant to have a Gulf Arab country as a warring party that struck Iran directly." Retired U.S. Air Force Lt. Gen. Dave Deptula framed it more bluntly: "If you have that capable of an air force, why would you sit back and absorb attacks from Iran without responding?"
That question answers itself. For years, the conventional wisdom held that Gulf states would never risk open conflict with Tehran. The escalating pressure campaign against Iran changed the calculus. When Iran struck first and struck hard, the Gulf states hit back.
What happened next matters as much as the strikes themselves. The combination of Saudi and Emirati military retaliation, diplomatic threats, and intensive back-channel contacts produced an informal understanding to de-escalate, before the broader ceasefire between Washington and Tehran took effect on April 7.
The numbers tell the story. After more than 105 attacks on Saudi Arabia in the week of March 25, 31, the tally dropped to just over 25 between April 1, 6. The Saudi Air Force strikes, combined with Riyadh's expulsion of Iranian diplomats and its summoning of Iraq's ambassador on April 12 to protest attacks from Iraqi soil, sent a message that Tehran apparently received.
Ali Vaez, the Iran Project Director at the International Crisis Group, said the sequence of retaliatory strikes followed by de-escalation would, if confirmed:
"Show pragmatic recognition on both sides that uncontrolled escalation carries unacceptable costs."
Vaez described the dynamic as "not trust, but a shared interest in imposing limits on confrontation before it spiralled into a wider regional conflict."
That framing, pragmatic restraint born of demonstrated willingness to fight, is the oldest lesson in deterrence. It stands in sharp contrast to the approach that preceded the current administration. The military buildup in the Strait of Hormuz signaled American seriousness. Gulf allies followed that lead.
The timeline leaves little room for ambiguity about who escalated first. After the February 28 U.S.-Israeli strikes on Iran, Tehran did not confine its response to military targets or to the countries that struck it. Iran hit all six Gulf Cooperation Council states, including nations that had no direct role in the initial campaign. It closed the Strait of Hormuz, one of the world's most critical shipping lanes, while the Red Sea remained open.
Iran fired 31 drones and 16 missiles at Saudi Arabia on April 7, 8 alone, according to the Saudi defence ministry, even as a ceasefire between Washington and Tehran was supposedly taking hold. Western sources assessed that some projectiles fired at Saudi Arabia originated from Iraqi territory, prompting Riyadh's formal protest to Baghdad.
Tehran's pattern of aggressive action even during ceasefire windows has been a recurring feature of this conflict. The Saudi and Emirati strikes did not emerge from a vacuum. They followed weeks of sustained bombardment of Gulf civilian and energy infrastructure, the kind of provocation that no sovereign nation could absorb indefinitely without responding.
The Saudi-Iranian relationship had been on a cautious upswing since a China-brokered détente in 2023 that saw the two countries resume diplomatic ties. That deal also produced a ceasefire between the Iran-backed Houthis in Yemen and Saudi Arabia, one that has held. Tehran's ambassador remained in Riyadh throughout the current crisis, and the two sides maintained regular diplomatic contact even as bombs fell.
An Iranian official involved in the contacts described the goal as an effort to "cease hostilities, safeguard mutual interests, and prevent the escalation of tensions." By the end of March, Western sources said, diplomatic contacts and Saudi threats of further retaliation had produced an understanding to de-escalate.
Former Saudi intelligence chief Prince Turki al-Faisal, writing in an op-ed in the Saudi-owned Arab News over the weekend, offered a revealing window into Riyadh's internal framing of events:
"When Iran and others tried to drag the kingdom into the furnace of destruction, our leadership chose to endure the pains caused by a neighbour in order to protect the lives and property of its citizens."
That language, patient endurance followed by decisive action, tracks with the broader pattern. Saudi Arabia absorbed punishment, warned publicly, expelled diplomats, and then struck. The wider American campaign against Iranian military leadership provided the strategic umbrella under which Gulf states could act with confidence.
Significant questions remain. Neither Saudi Arabia nor the UAE has publicly acknowledged the strikes. The exact targets of the Saudi Air Force attacks inside Iran have not been disclosed. Whether there were casualties from either the Saudi or Emirati operations is unknown. No formal written de-escalation agreement between Riyadh and Tehran has been confirmed.
The New York Post reported that the Saudi strikes, combined with intensive diplomacy and threats of further retaliation, helped pressure Iran into the de-escalation understanding that preceded the broader April 7 ceasefire. If that assessment holds, it would mean that Gulf military action, quiet, calibrated, and backed by American resolve, played a direct role in winding down the most dangerous phase of the conflict.
The UAE's expanded military cooperation with the United States, reported by the Wall Street Journal, suggests the Gulf realignment is not a one-off reaction but a structural shift. These are countries that spent decades hedging between Washington and Tehran. Iran's indiscriminate bombardment of all six GCC states forced a choice. They chose.
For years, the foreign policy establishment insisted that confronting Iran would destabilize the Gulf and drag reluctant allies into a war they couldn't handle. What actually happened was the opposite. Iran attacked first. Gulf states absorbed the initial punishment, then struck back with precision. The diplomatic track with Tehran continued in parallel. And the violence de-escalated, not because anyone begged for peace, but because both sides recognized the cost of continuing.
The attack count dropped from 105 in one week to 25 the next. That did not happen because of a sternly worded UN resolution.
Deterrence works when the people doing the deterring are willing to back it up. Saudi Arabia and the UAE just demonstrated that they are. The question now is whether Iran learned the lesson, or whether it will need to be taught again.
