The U.S. State Department issued a “Worldwide Caution” alert for American citizens, flagging the potential of travel disruptions and demonstrations following the U.S. strikes on Iranian nuclear facilities.

“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 a statement. “There is the potential for demonstrations against U.S. citizens and interests abroad. The Department of State advises U.S. citizens worldwide to exercise increased caution.”

These global alerts from the U.S. are relatively rare — the last one was in October 2023, soon after Hamas’ attacks on Israel from Gaza sparked the latest conflict.

Iran has vowed to retaliate after the U.S. attacked its facilities over the weekend in a bid to derail the country’s nuclear program. Iran’s foreign minister has said it reserves all options to respond, and the Islamic Revolutionary Guard Corps has signaled that U.S. military bases in the region could be targeted.

At the United Nations on Sunday, Iranian Ambassador Amir Saeid Iravani told an emergency Security Council meeting that the “timing, nature and scale” of Tehran’s response “will be decided by its armed forces.”
