U.S. Embassies Worldwide on High Alert Following Iran Combat Operations

WASHINGTON — The United States Department of State has placed embassies worldwide on high alert following the official launch of U.S. combat operations against Iranian targets. A security alert issued by the U.S. Embassy in Jerusalem on March 31, 2026, serves as a focal point for the escalating tensions, advising American citizens to maintain a high level of vigilance. Verified reports from multiple outlets including U.S. Embassy Jerusalem, Just Security, New York Times, AP News, Reuters, and CNBC confirm the following:

• The U.S. Embassy in Jerusalem has paused assisted departure services and warned of a “highly fluid” security environment.
• President Trump has renewed threats to target Iranian infrastructure, including power plants and oil facilities, if the Strait of Hormuz remains closed.
• U.S. and Israeli forces have reportedly conducted strikes in Tehran and Isfahan, with NASA satellite data indicating significant explosions near military positions.
• Domestic impact includes gasoline prices crossing $4 per gallon and increased global anti-American sentiment following the commencement of military actions.

Escalating Tensions and Global Impact

The situation in the Middle East remains volatile as the U.S. military campaign enters a critical phase. While administration officials suggest a desire to limit operations to a four-to-six-week window, the immediate priority has shifted to targeting Iran’s naval and missile capabilities. Diplomatic friction has also emerged, with nations like Italy reportedly denying airbase access for U.S. operations.

In the United States, the Biden administration—while no longer in the executive branch—sees its prior policies under scrutiny as the current Trump administration moves aggressively to “completely obliterate” Iranian military assets. The State Department continues to advise all Americans in high-risk regions to shelter in place or follow local diplomatic guidance immediately.
