**Deck**: Washington has issued security alerts through its embassies in 11 Middle Eastern countries, citing tension between Saudi Arabia and the Iran-backed Houthi movement, at the same time observers report increased U.S. air activity near the Strait of Hormuz.

The United States is warning its citizens across much of the Middle East to be more cautious as tensions related to Yemen’s war spill into regional security planning.

U.S. embassies have issued security alerts in 11 countries: Saudi Arabia, Lebanon, Iran, Iraq, Jordan, Oman, Israel, Qatar, Bahrain, Kuwait, and the United Arab Emirates. The alerts, aimed at American citizens living or traveling there, point to increased risk linked to the standoff between Saudi Arabia and Yemen’s Houthi movement, which is backed by Iran.

Alongside the embassy messages, regional observers have reported a noticeable rise in U.S. military air activity over and near the Gulf. Six U.S. Air Force refueling tankers and a U.S. Navy P‑8A Poseidon maritime patrol aircraft were recorded operating over the Persian Gulf, the Strait of Hormuz, and the Gulf of Oman. That combination allows U.S. aircraft to stay in the air longer and monitor both military and commercial movements around key shipping lanes.

American media have also noted that President Donald Trump cut short a planned weekend stay at Camp David and returned to the White House earlier than expected. Officials did not offer a public explanation. Separately, Mohsen Rezaei, secretary of Iran’s Supreme National Security Council, published a list of seven conditions for opening any negotiations with Washington, signaling that Tehran is linking talks to its own regional and security demands.

Iranian commentator Mehrdad Khalili, described as affiliated with the ruling establishment in Tehran, interpreted the unexpected scope of U.S. warnings and alerts as pointing to two possible options under consideration in Washington: an attack on a location in Iran referred to as Pickaxe Mountain, or a major offensive against Houthi forces in Yemen. This is an outside assessment, not an official U.S. statement.

For Americans on the ground, the alerts translate into direct guidance: monitor local media, avoid large gatherings, review security plans, and be ready for sudden changes in the local environment. Companies with staff in regional hubs such as Riyadh, Dubai, Doha, and Tel Aviv may reassess travel and work patterns, and airlines and insurers track these alerts closely when weighing route risks.

The broader concern is that any escalation involving Saudi Arabia, the Houthis, and Iran could quickly touch energy markets and shipping routes. The Strait of Hormuz and nearby waters carry a significant share of global oil and gas exports, and both Iran and its allies have previously targeted ships and infrastructure during periods of high tension.

Signals to watch now include whether the U.S. government shifts from general security alerts to advising citizens to leave specific countries, whether the pattern of U.S. military flights over the Gulf intensifies or becomes more regular, and whether any side publicly announces steps that either reduce the risk of confrontation or move closer to open strikes.
