Iran Warns of Retaliation:
Iran has also threatened to target US military installations and allies in the region if they support such attacks in the future. “Any country used by the US to strike Iran will be a legitimate target for our armed forces,” said Ali Akbar Velayati, an advisor to Iran’s Supreme Leader Ayatollah Ali Khamenei.
Worldwide Caution Alert:
The US State Department warned citizens to exercise caution in its “Worldwide Caution” advisory, particularly in regions where protests or other disturbances might take place. Travel difficulties and potential closures of Middle Eastern airspace were cited in the advisory.
The alert said, “The Department of State advises US citizens worldwide to exercise increased caution,” and advised passengers to visit the official website for updates and information.
Regional Advisories:
Turkiye: The U.S. Embassy has instructed its employees to avoid all 22 provinces in southeast Turkey, including the Adana region. It warned of rising anti-American sentiment, citing potential boycotts, protests, and anti-U.S. graffiti. The embassy urged Americans in Turkey to stay away from locations linked to the United States, Israel, or other Western countries, monitor local news, and steer clear of any protests.
Lebanon: Citing the deteriorating security situation, the U.S. ordered non-essential employees and their families to evacuate Beirut. Some airlines have canceled or suspended their services, though flights continue to operate. Officials urged citizens to monitor the situation closely and leave the country as soon as commercial travel options become available.
Saudi Arabia: Officials cautioned Americans against visiting military installations in the region and advised them to prepare for unforeseen circumstances. They urged the public to review emergency plans and keep travel schedules flexible. The advisory emphasized, “A good plan helps you think through potential scenarios because crises can happen unexpectedly.”
Suspended Airlines Operations:
The State Department urged tourists to prepare for border closures, airspace delays, and possible protests near U.S. embassies and Western-linked sites. It advised people to monitor local media, avoid crowds, and follow the latest travel guidance from their home countries. The warning stressed the importance of having a plan and staying alert, stating, “Crises can happen unexpectedly while traveling or living abroad.”
Israel-Iran Conflict:
As Israel continues striking Iranian targets, including missile bases and infrastructure in Tehran, Hamedan, and Kermanshah, the U.S. has responded by issuing travel advisories. In retaliation, Iran launched long-range missile strikes against Israel and vowed further reprisals. Iran’s envoy to the UN accused the United States of “destroying diplomacy.” Some Iranian officials acknowledged that the strikes damaged the nuclear program but did not destroy it. “The game isn’t over even if nuclear sites are destroyed,” wrote senior Iranian advisor Ali Shamkhani.
