The Associated Press has characterized the week’s assaults on Saudi Arabia as “the new front in the Iran war.” Saturday’s strike fit that description on the sourced record: a missile struck Riyadh’s international airport, hitting a complex housing terminals 3 and 4 for domestic flights, and a regional official, speaking on condition of anonymity because they were not authorized to speak to the media, said many people were wounded. It was the latest in a surge that, according to the AP, has come in the week since a Saudi-led coalition launched a major military offensive against the Houthis, with strikes hitting other Saudi airports, military facilities and oil infrastructure.

President Donald Trump said the United States was evaluating whether to join the Saudi strikes. “We may. We’re going to look at it,” Trump said of intervening. “We just found out about the recent attack. So we’ll make a decision. We move very quickly.” The documented record of U.S. involvement, as officials have described it, has included intelligence sharing, target identification and planning for the latest offensive against the Houthis. The Houthis have told the AP and others that they are only targeting Saudi shipping as part of a blockade in retaliation for one imposed on them; the group previously attacked other ships after the war in Gaza began, calling it solidarity with Palestinians, and a U.S. bombing campaign sharply limited that, according to the AP.

The defense layer in the kingdom is reported to be under strain. Regional officials told the AP last month that Saudi Arabia is running low on missile interceptors and has asked France, Britain, Pakistan and Egypt to deploy air defense support, with one official noting that the United States has seen its own stock dwindle during the war with Iran. The European Union Aviation Safety Agency expanded its guidance on Saudi airspace, noting the Houthis’ ability to strike targets deeper inside the kingdom, including Riyadh, and a “greater focus on aviation infrastructure”; the missile and drone attacks and interception efforts, the agency said, “create an increased risk of misidentification of civil aircraft.” Two regional officials said Houthi attacks on the Riyadh airport on Thursday damaged three planes; the Saudi national carrier said one of its aircraft was damaged while on the ground, with no passengers on board.

The scene at the airport on Saturday carried the markers of a civilian node under military stress: Saudi civil aviation authorities suspended operations through midnight, the airport was under heavy police presence, all entrances were blocked and lights around the complex were dimmed, and the Flightradar24 tracker said flights were being diverted elsewhere. At least 291 flights had been canceled over the past 24 hours, according to flight-tracking site FlightAware. Before the latest attack, Air India, FlyDubai, Lufthansa Group and Pakistan International Airlines were among airlines suspending flights to and from Riyadh and other Saudi airports for varying periods. The United States, Britain, Germany, Australia and Canada warned citizens to avoid the airport. Hours after the latest strike, the Saudi energy ministry was still promoting a major international energy conference set to begin in Riyadh on Sunday; the attacks on Saudi Arabia, the world’s top oil exporter, have rattled markets and the region, the AP reported.

Saturday’s attack came after the Houthis accused Saudi Arabia earlier Saturday of striking Sanaa International Airport in the Houthi-held Yemeni capital, and followed Houthi claims, earlier in the week, of attacks on King Khalid International Airport that killed three Saudis, including a pilot; there was no immediate statement from the rebels about Saturday’s strike. The Houthis this week warned global airlines “for the last time” about the potential consequences of operating in Saudi airspace, which they described as a theater for their military operations. Saudi authorities, meanwhile, warned the public that “filming, publishing or sharing information related to countering missiles and drones and their impact sites exposes you to legal liability.”

Fighting in Yemen between the Houthis and Saudi-backed Yemeni government forces has escalated, with the Saudi-led coalition providing air support for government forces attempting to reverse recent Houthi gains along the Red Sea. Those gains, in the AP’s account, gave the rebels better surveillance of shipping on a corridor that is a crucial alternative to the Strait of Hormuz, where Iran has been attacking ships; concerns about wider attacks persist, the AP reported, even as the Houthis have described their targeting as a blockade in retaliation for one imposed on them. On Saturday, Saudi Arabia said its foreign minister and Omani counterpart spoke by phone about the importance of “supporting diplomatic solutions to de-escalate tensions” in the region; Oman, which lies across the Strait of Hormuz from Iran, has played a mediator role at times in the region.

The public record around Saturday’s strike supports a working description of the moment: the campaign has entered, in the AP’s phrase, “the new front in the Iran war”; the kingdom’s capacity to sustain it is reported by regional officials to be under strain; and Washington has described its role as assistance already provided — intelligence sharing, target identification and planning — while the decision to join the strikes remains, in the president’s words, something the United States “may” pursue.
