The U.S. State Department updated its travel advisory summary for the Middle Eastern island nation of Bahrain and kept the “Level 3-Reconsider travel” designation because of armed conflict and terrorism threats.

The updated warning reflects the intensifying conflict scenario in the region as Houthis increase their offensive against Saudi Arabia.

“Iranian-supported Houthis have engaged in hostilities against Saudi Arabia, including attacks on civilian airports and other critical infrastructure resulting in civilian casualties and severe travel disruptions,” the department said in the Oct. 23 update.

“The hostilities have the potential to escalate rapidly beyond that immediate area,” the department warned, referring to Bahrain and other Middle East countries bordering Saudi Arabia.

The advisory update said there is a higher risk of potential armed attack from Houthis, as well as Iranians targeting U.S. government officials in the region. Currently, U.S. government employees require special authorization to travel to Bahrain because of safety risks.

Terrorists continue to plot potential attacks in Bahrain and may act with little to no warning, with targets likely including religious sites, transportation hubs, tourist sites, shopping malls, government and military facilities, and markets, the advisory said.

The U.S. Embassy in Saudi Arabia had warned in an Oct. 21 security alert about the risk of conflict escalation.

“U.S. citizens should be aware of potential attacks on airports, airspace closures, flight cancellations, and travel disruptions. Please take extreme caution if you choose to use airports in Saudi Arabia. We recommend checking your flight departure status directly with the airline and with the airport,” the alert said.

Saudi Arabia’s Ministry of Interior has warned against filming, sharing, or publishing information related to counter missiles and drones, as well as their impact sites. Americans have been detained for not following these regulations, the alert said.

On Wednesday, the State Department ordered non-emergency government employees and their families in Saudi Arabia to leave the country amid Houthi attacks. These attacks have targeted civilian airports and other critical infrastructure, which has disrupted travel and led to casualties.

The Saudi Civil Aviation Authority announced on Thursday that a resident was killed in an attack on the King Fahd International Airport in Dammam.

In a sign of widening conflict, Egyptian President Abdel Fattah El-Sisi has called for an urgent parliamentary session to authorize military aid for Saudi Arabia. Parliament is set to vote on Oct. 26.

“Egypt has never shirked its Arab role in protecting Arab national security, and Saudi Arabia, for us, is a part of Egyptian national security, and any threat to its security and stability is a threat to us,” Egyptian lawmaker Mostafa Bakry said in an Oct. 18 post on X.

Amid the rising tensions in the Middle East, the State Department updated travel advisories for other countries in the region on Oct. 23 in addition to Bahrain. The advisories covered Saudi Arabia, Iraq, Jordan, Kuwait, Lebanon, Oman, Qatar, Syria, the United Arab Emirates, and Yemen.

The U.S. Federal Aviation Administration issued a notice due to risks of operating civil aviation within or near the Gulf of Oman and the Persian Gulf region, including Bahrain.

Meanwhile, a July 22 worldwide caution security alert for U.S. citizens, issued by the State Department due to Middle East tensions, remains in effect.

The alert asked Americans outside the Middle East to reconsider travel through and to the region. Those who do travel must monitor information about airline and airport operations, the alert said.

“U.S. diplomatic facilities, including outside the Middle East, have been targeted. Iran and groups supportive of Iran may target other U.S. interests overseas or at locations associated with the United States and Americans throughout the world, including U.S. businesses and other institutions,” the alert said.
