Saudi Arabia has experienced a resurgence of attacks by cross-border militants, including Houthis, who have claimed responsibility for targeting a number of strategic facilities. Yahya Saree, who was with the Houthis, declared that the group attacked the King Khalid International Airport in Riyadh, the Rabigh oil refinery, crude oil pumping stations and the East-West Pipeline. The militant group also said it had attacked an Aramco site in Yanbu.

The coordinated attack reportedly included attacks on King Fahd International Airport in Dammam as well as an airbase in Khamis Mushait and an airport in Najran. There hasn’t been any immediate confirmation of whether these particular targets were struck by the Saudi-led coalition but the Ministry of Defense of Saudi Arabia said that on Saturday, the coalition successfully intercepted and destroyed two ballistic missiles aimed at the cities of Yanbu and Taif.

The General Directorate of Civil Defense issued some emergency notifications alerting residents to possible danger in Taif, Yanbu, Mecca and Jeddah for a few moments, as tensions escalated. The agency later confirmed that the threat was over in about ten minutes.

The renewed hostilities have obliterated a 2022 truce that had succeeded in suspending most cross-border attacks between the Saudi-led anti-Houthis coalition and the Houthis’ control of the Yemeni capital of Sanaa, mediated by the United Nations. This violent escalation effectively has added another front to the bigger U.S.-Israeli war against Iran.

This conflict has also escalated inside Yemen. Two Houthi missiles fired at a headquarters of the coast guard and a third at another separate coast guard building in the Tawahi district of Sanaa hit the internationally recognized government’s interior ministry, the ministry said in a press release. In the meantime, the Houthis said their troops had attacked Saudi-backed military meetings in the Al-Nasr camp and a naval base in Aden, which they said were being conducted by Saudi officers. The Saudi-led coalition has yet to respond to this claim.

Adding to the difficulties in regional travel, earlier this month the Houthis warned airlines not to use Saudi airspace as they ramped up their attacks. The militants indicated that they would not attack the airspace over Mecca or Medina, but this has led to significant security worries for aviation authorities such as the General Authority of Civil Aviation, as well as international airlines flying in the area.
