US Embassy in Kyiv Closes Amid Significant Air Attack Threat

The U.S. Embassy in Kyiv has temporarily closed due to warnings of a potential significant air attack, advising U.S. citizens to be ready to shelter. This comes amid heightened tensions following Ukraine's use of U.S.-made long-range missiles against Russia, and Russia's updated nuclear doctrine suggesting a possible nuclear response to Western non-nuclear attacks. The situation is further complicated by accusations from Russia that the U.S. is prolonging the conflict, while Ukraine continues to face drone and missile attacks from Russia.
