After a joint U.S.-Israel attack that killed Iranian Supreme Leader Ayatollah Khamenei, retaliatory attacks on sites across the Middle East have continued. International airports in Dubai and Abu Dhabi, Kuwait, and Bahrain have all been targeted by Iranian drone attacks. Foreign affairs ministries in different countries have issued travel advisories warning citizens to avoid traveling to the region due to the ongoing threat of drone and missile attacks from Iran. The State Department has also ordered all non-critical U.K. government workers in the two countries to leave along with their families, a day before the strike, Israel's case was the day before. Meanwhile, the United Kingdom, Canada, Australia, Germany, France and Cyprus have issued similar advisories.
