The U.S. State Department is warning Americans to be especially careful while traveling overseas as rising tensions across the Middle East create the possibility of further violence and widespread travel disruptions.

The agency issued a rare worldwide caution Saturday afternoon following Iranian attacks on Jordan that killed two U.S. service members. A third service member was reported missing in action after the wave of ballistic missile and drone attacks, according to U.S. Central Command.

“Due to high tensions in the Middle East, the security environment remains complex with the potential for unforeseen escalation,” the State Department said.

While the alert places particular focus on the Middle East itself, the message applies to Americans around the globe. Officials warned that groups aligned with Iran could target U.S. citizens, diplomatic facilities and other American interests in destinations both within and outside the region.

“Groups supportive of Iran may target other U.S. interests overseas or locations associated with the United States and/or Americans throughout the world,” the alert added.

Americans traveling abroad are being advised to exercise “increased caution” and pay close attention to security alerts from the nearest U.S. embassy or consulate. Travelers should also be prepared for possible airspace closures, canceled flights and other last-minute disruptions stemming from the conflict.

The worldwide caution follows a separate State Department warning focused on Saudi Arabia, where Iranian-backed Houthis recently launched a ballistic missile at an airport. The New York Post reported that the missile was intercepted before it could cause damage.

“Americans should reconsider any travel to Saudi Arabia and reconsider travel to/through the Middle East,” the agency advises.

Saudi Arabia has carried a Level 3: Reconsider Travel advisory since March. That is one step below Level 4: Do Not Travel, the State Department’s most serious warning. Iran, Iraq and Israel have been under Level 4 advisories for months.

The latest alerts come as relations between the United States and Iran continue to deteriorate. Iran’s Deputy Foreign Minister Kazem Gharibabadi said Saturday that Tehran had stopped honoring its commitments under a recent memorandum of understanding after accusing the United States of failing to meet its own obligations.

“We have … suspended our commitments, we are not implementing them, and we are busy defending the country,” Gharibabadi said.

Before traveling internationally, Americans should review the State Department advisory for their specific destination and enroll in the free Smart Traveler Enrollment Program (STEP) to receive security updates and make it easier for U.S. officials to reach them during an emergency.
