Americans traveling abroad are being urged to exercise caution worldwide, as the war between Israel and Iran has resulted in travel disruptions globally.

The U.S. State Department issued a warning to those traveling around the world, citing the potential for demonstrations against U.S. citizens.

“The conflict between Israel and Iran has resulted in disruptions to travel and periodic closure of airspace across the Middle East,” the State Department said in its Worldwide Caution advisory. “There is potential for demonstrations against U.S. citizens and interests abroad. The Department of State advises U.S. citizens worldwide to exercise increased caution.”

Last week, the State Department warned U.S. travelers to not travel to places like Israel, Gaza and the West Bank because of armed conflict, terrorism and civil unrest.

After the bombing, Iranian officials warned of retaliation against the U.S.

The State Department often issues alerts and travel advisories for Americans overseas.

The travel advisories range from “exercise normal precaution” to “Do Not Travel,” which is reserved for parts of the world where there is ongoing conflict, ethnic or religious discrimination or where U.S. citizens are generally not welcome.

Other reasons for alerts include crime rates, health concerns and piracy in some parts of the world.
