Deadly security risks prompt updated travel warnings for 13 countries

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.
