The U.S. State Department has updated travel advisories for several Middle Eastern countries, warning of potential armed attacks by Iranian-backed Houthi forces and threats targeting Americans.
Five countries — Iran, Iraq, Lebanon, Syria and Yemen — are listed under the department’s highest advisory level, Level 4, which warns Americans not to travel.
Eight others, including Israel, Qatar and the United Arab Emirates, are designated Level 3, urging travelers to reconsider their plans.

While the advisory levels largely remained unchanged, all 13 advisories were updated on Friday.
The advisories cited recent attacks by Iranian-supported Houthis, including strikes on Riyadh’s airport in Saudi Arabia and “other critical infrastructure,” the department said.
The attacks have resulted in civilian deaths and widespread travel disruptions, with the State Department warning that the hostilities “have the potential to escalate rapidly beyond that immediate area.”

Last week, the State Department raised its travel advisory for Kenya from Level 2, “Exercise Increased Caution,” to Level 3, “Reconsider Travel,” citing health risks, crime, civil unrest, kidnapping and terrorism.
At around the same time, officials warned Americans traveling to China of the risk of wrongful detention, electronic surveillance and restrictions that could prevent them from leaving the country.
