WASHINGTON, DC: The US Department of State on Saturday, February 28, urged US citizens worldwide to “exercise increased caution” following US and Israeli military strikes against Iran.

In a worldwide caution alert, the department said that Americans, particularly those in the Middle East, should closely follow the latest security guidance from the nearest US embassy or consulate.

“Following the launch of US combat operations in Iran, Americans worldwide and especially in the Middle East should follow the guidance in the latest security alerts issued by the nearest US embassy or consulate,” the alert said.

Airspace closures and travel disruptions possible

The advisory warned of potential travel disruptions due to periodic airspace closures in parts of the region.

“They may experience travel disruptions due to periodic airspace closures,” the alert said, reiterating that Americans should remain vigilant.

US citizens abroad were also encouraged to enroll in the Smart Traveler Enrollment Program (STEP) and to follow official security update channels on WhatsApp for real-time information.

The State Department noted that it issued a similar worldwide caution alert last June, coinciding with earlier US strikes on Iranian nuclear facilities.

Trump consults regional and NATO leaders

Following the launch of US military operations, Donald Trump held calls with several international leaders, according to White House Press Secretary Karoline Leavitt.

“President Trump has spoken with the leaders of Saudi Arabia, Qatar, UAE, and the NATO Secretary General Mark Rutte,” Leavitt wrote in a post on X.

She also confirmed that Trump spoke earlier with Benjamin Netanyahu, underscoring close coordination with Israel amid the escalation.

US Central Command reports no US casualties

The US Central Command said the United States had not suffered any combat-related casualties in the operation against Iran.

In a statement, CENTCOM said damage to US installations was minimal and had not affected military operations.

The command said the operation, launched early Saturday morning, was aimed at dismantling Iran’s security apparatus and focused on sites deemed to pose an imminent threat.

According to CENTCOM, targets included IRGC command-and-control facilities, Iranian air defense systems, missile and drone launch sites, and military airfields.

“The President ordered bold action, and our brave Soldiers, Sailors, Airmen, Marines, Guardians, and Coast Guardsmen are answering the call,” said Adm Brad Cooper, the commander of CENTCOM.

US officials said operations remained ongoing, while diplomatic and security advisories continued to be updated for Americans abroad.
