U.S. embassy in Kyiv closes due to warnings of Russian air attack

The U.S. Embassy in Kyiv has closed due to warnings of a significant Russian air attack. Employees have been instructed to shelter in place, and U.S. citizens in the area are advised to be ready for air alerts. This warning follows increased Russian missile and drone attacks on Kyiv. It comes after Ukraine used U.S.-made long-range missiles to strike a target in Russia, prompting a response from Moscow regarding its nuclear policy. Russia has recently intensified its air assaults, targeting energy infrastructure as winter approaches. The situation remains tense, with concerns about the implications of Ukraine's new military capabilities and Russia's revised nuclear stance.
