Riyadh, Saudi Arabia, faced two air-raid warnings in the early hours of today, September 19, marking the first time the country's capital has seen such alerts since the period when war between the United States and Iran intensified in March and April. Saudi Arabia's early-warning system issued an emergency alert in Riyadh at 4:00 a.m. and again at 6:00 a.m., without disclosing further details. Meanwhile, Saudi Arabia's civil defense authority said the danger had ended shortly after both alerts. Other areas across the country received similar warnings throughout the past night, including Jeddah and Yanbu on the Red Sea, as well as Farasan Island in the Red Sea. The warnings came amid a new wave of attacks Saudi Arabia has faced in September, with the Iran-backed Houthis based in Yemen striking cities in western Saudi Arabia, including energy infrastructure, over the past week. The Saudi government said a drone attack from Iraq, home to several Iran-backed armed groups, forced the East-West oil pipeline to halt operations. In addition, attacks on the pipeline and Iran's closure of the Strait of Hormuz have sharply reduced Saudi Arabia's oil exports and created further problems for Crown Prince Mohammed bin Salman, the kingdom's leader. The renewed conflict also risks affecting Saudi Arabia's efforts to attract investment and tourists, part of its push to diversify the country's economic structure. In October, Riyadh is scheduled to host Saudi Arabia's flagship investment conference, the Future Investment Initiative, with the 2026 annual gathering set to welcome several senior Wall Street executives, including JPMorgan Chase & Co CEO Jamie Dimon and David Solomon of Goldman Sachs Group.

The United States has reached an agreement with Greenland and Denmark that will open the way for the US to permanently expand its military and security role on the island of Greenland, while blocking the influence of adversary nations. The three parties are expected to sign jointly during the United Nations General Assembly in New York next week, and the new agreement will replace the 1951 Greenland Defense Agreement. The US State Department stated that the agreement will prohibit countries that are not members of the North Atlantic Treaty Organization, or NATO, from establishing bases or stationing troops in Greenland, and will also bar non-allied countries from investing in mining and critical minerals. These conditions appear aimed at blocking China or Russia from accessing resources or establishing military footholds in Greenland. President Donald Trump posted a message stressing that the United States will be able to do everything necessary to ensure stability and protect the security of Greenland, as well as that of the United States, and confirmed that this is not a transfer of sovereignty or a cession of territory to the US. Meanwhile, Mette Frederiksen, the Prime Minister of Denmark, and Jens-Frederik Nielsen, the Prime Minister of Greenland, confirmed the agreement through a joint statement, with Frederiksen stating that the agreement will help strengthen security in the Arctic and North Atlantic region, while affirming the sovereignty and territorial integrity of the Kingdom of Denmark, as well as the right of Greenlanders to determine their own future.
