Saudi Arabia issued an all-clear in the capital Riyadh on Saturday after authorities warned residents of a potential aerial attack, as tensions escalated between the kingdom and Yemen's Houthi movement.
Saudi Civil Defence sent emergency alerts to residents of Riyadh and the nearby city of Al-Kharj during the early hours of Saturday, warning of a potential aerial threat and instructing people to follow safety instructions. The warning was later lifted after authorities determined that the immediate danger had passed.
The alert came after explosions were heard in Riyadh and a large column of black smoke was seen rising near King Khalid International Airport. Reuters footage showed smoke in the vicinity of the airport, while flames were visible at one point behind what appeared to be fuel-storage tanks. An AFP journalist later reported seeing firefighters dealing with a burning fuel tank bearing the logo of Saudi oil company Aramco.
Saudi authorities did not immediately provide a detailed explanation for the smoke or confirm whether the reported fire was directly connected to the aerial threat. However, the Saudi-led coalition fighting the Houthis said its air defences had intercepted and destroyed a missile launched toward Riyadh. The coalition also said it had thwarted attacks aimed at civilian areas in the cities of Baysh, Farasan and Taif, as well as Yanbu on the Red Sea coast.
Yemen's Houthi movement later claimed responsibility for attacks targeting what it described as sensitive sites in Riyadh. The group said it had used missiles and drones in the operation and also claimed to have targeted facilities belonging to Aramco in the Red Sea port city of Yanbu.
The Houthis said the attacks were carried out in response to what they described as Saudi attacks against their forces in Yemen's capital, Sanaa. The claims could not independently establish the extent of damage to the reported targets.
Saturday's warning was particularly significant because it was the first such alert issued for Riyadh since the latest escalation involving the Houthis began in July. Saudi Arabia has faced periodic missile and drone threats in previous years, but the current conflict has expanded the security risks facing the kingdom and its vital energy infrastructure.
The latest confrontation is part of a wider escalation across the Middle East. The Houthis, who control Yemen's most populous areas and much of the country's north, have intensified attacks against Saudi Arabia since July, including attacks involving Red Sea shipping. The group has also declared what it describes as a naval blockade against Saudi Arabia.
The renewed fighting has raised concerns about international energy supplies because Saudi Arabia is one of the world's largest oil exporters and relies on maritime routes through the Red Sea as an alternative route for some exports when the Strait of Hormuz is disrupted.
The situation around Riyadh also affected air travel. Flight-tracking service Flightradar24 reported major disruption at King Khalid International Airport, including delays and cancellations, as the security situation developed.
Residents in Riyadh reported hearing explosions during the period covered by the warning. A Reuters journalist in the Olaya area of the capital also heard booms before the all-clear was issued. Saudi authorities urged residents to continue following Civil Defence instructions and to avoid gathering or filming in affected areas.
The United States has also issued a security warning to Americans in the Middle East in response to the escalating Houthi attacks. The U.S. State Department urged Americans in the region to exercise heightened vigilance and advised those outside the region to seriously reconsider travel to and through the area.
The escalation has placed additional pressure on Saudi Arabia to strengthen its air-defence capabilities. Turkey's foreign minister said on Saturday that Saudi Arabia could have military needs because of the continuing Houthi attacks and that Turkey was prepared to provide assistance under a trilateral defence arrangement involving Turkey, Saudi Arabia and Pakistan.
Saudi Arabia has also sought broader international support as the security situation deteriorates. The United Nations Security Council has condemned Houthi attacks affecting Saudi civilian and energy infrastructure and expressed concern over the wider military escalation in Yemen. The council has called for an end to the attacks and supported efforts toward a negotiated political settlement.
The current conflict is also affecting an already fragile humanitarian situation in Yemen. The renewed fighting has displaced large numbers of people, while intensified military operations and the expansion of the conflict along the Red Sea have increased concerns about humanitarian access and civilian safety.
For Saudi Arabia, the attacks present a dual challenge. Authorities must protect major population centres such as Riyadh while also securing energy facilities, airports, ports and shipping routes that are essential to the country's economy.
For the Houthis, attacks on Saudi territory represent an expansion of their military campaign beyond Yemen's borders. The group has sought to use missiles, drones and attacks on shipping as part of its broader strategy in the regional conflict.
The latest events also carry international economic implications because any sustained disruption to Saudi oil infrastructure or Red Sea shipping could affect global energy prices and supply chains. The Red Sea is an important maritime corridor linking the Indian Ocean with the Mediterranean through the Suez Canal, while Saudi Arabia remains a major supplier to global oil markets.
Despite the dramatic scenes around Riyadh, Saudi authorities have not reported casualties from the intercepted missile attack. The Saudi-led coalition said the missile aimed at the capital was destroyed, while the full circumstances surrounding the smoke and fire near the airport remain under investigation.
The immediate danger warning has now been lifted, but the broader security situation remains tense. The Houthis have vowed to continue their military campaign, while Saudi Arabia has intensified defensive measures and sought support from regional and international partners.
The Saturday alert therefore represents more than an isolated security incident. It is another indication that the conflict involving Saudi Arabia and the Houthis has entered a more dangerous phase, with the potential to affect civilians, aviation, energy infrastructure and international shipping across the wider Middle East.
