The United States closed its embassies in Saudi Arabia and Kuwait on Tuesday after both facilities came under drone attacks from Iran, as the conflict between Washington, Jerusalem and Tehran entered its fourth day.

The U.S. Embassy in Riyadh announced it was closed for the day, canceling all routine and emergency American citizen services appointments, and urged Americans to avoid the compound due to an attack on the facility. Saudi Arabia's Defense Ministry reported that two drones struck the embassy, causing limited fire and minor material damage but no injuries. The kingdom condemned the strike as a "cowardly and unjustified attack" in violation of international law protecting diplomatic sites.

In Kuwait, the U.S. Embassy halted all visa and citizen services appointments until further notice following a drone strike on its compound on Monday. Kuwaiti state media described the incident as a "brutal" Iranian attack, and the embassy instructed staff and citizens to shelter in place. Kuwaiti airspace remained closed, though the land border with Saudi Arabia was open, allowing Americans to apply for e-visas there.

The closures came amid broader U.S. evacuation orders. The State Department directed nonessential personnel and families to depart Bahrain, Iraq, Jordan, Kuwait, Qatar and the United Arab Emirates. Assistant Secretary of State Mora Namdar urged Americans across the Middle East to "DEPART NOW" from countries including Egypt, Iraq, Jordan, Syria, the UAE and Qatar due to serious safety risks.

The attacks marked Iran's retaliation for U.S.-Israeli strikes that began on February 28, killing Supreme Leader Ayatollah Ali Khamenei and dozens of top Iranian officials. President Donald Trump stated on Truth Social that U.S. bombing would continue "uninterrupted throughout the week or as long as necessary" to achieve peace. Six American service members have been killed so far, with Trump warning of more potential casualties.

Iran has launched hundreds of missiles and drones at U.S. air bases in Gulf states including the UAE, Qatar and Bahrain, as well as Jordan, with most intercepted. Saudi defenses downed eight drones near Riyadh and Al-Kharj on Tuesday. The U.S. also closed its embassy in Beirut, Lebanon.

Embassy alerts emphasized sheltering in place, monitoring local media, enrolling in the Smart Traveler Enrollment Program and following local authorities. The State Department continued to monitor the situation as commercial flights faced disruptions across the region.
