The US Embassy in Jordan issued a travel advisory on Friday to Americans in the Middle East in light of current hostilities in the region, specifically pointing to the recent Houthi attack on Saudi Arabia's Riyadh airport.
"Iranian-supported Houthis have engaged in hostilities against Saudi Arabia, including attacks on civilian airports and other critical infrastructure resulting in civilian casualties," the embassy wrote, adding that "the hostilities have the potential to escalate rapidly" and Americans should monitor the situation closely, particularly if they are planning travel to or from the region.
Also on Friday, the European Union Aviation Safety Agency EASA recommended airlines not to operate within additional portions of Saudi airspace after Yemen's Iran-aligned Houthis attacked Riyadh airport.
In an updated conflict zone information bulletin for Saudi Arabia airspace, which was initially issued on September 30, the EU regulator said recent attacks had demonstrated the ability and intent of the Houthis to strike targets deeper inside Saudi territory, including the capital.
Three killed, several wounded following two attacks on Saudi Arabia's King Khalid airport
The situation escalated after Saudi Arabia's General Authority of Civil Aviation said on Friday that three Saudi nationals were killed and several people were wounded following two attacks on King Khalid International Airport in Riyadh on Thursday.
In a statement on X/Twitter, the General Authority of Civil Aviation said the first attack targeted airport facilities, while the second struck an aircraft belonging to Saudi state carrier Saudia.
Yemen's Iran-aligned Houthis said on Thursday they had attacked the airport with two cruise missiles.
The group also said it had targeted an airport in the southwestern city of Najran, a claim Saudi authorities have not confirmed, and an airbase in Khamis Mushait with ballistic missiles.
The Houthis say they are targeting the kingdom over its support for government forces in Yemen's reignited civil war. Saudi Arabia says it is backing an offensive by Yemen's UN-recognized government to take back territory from the Houthis.
