U.S. closes embassy in Kyiv over warning of potential air attack

The U.S. has closed its embassy in Kyiv due to a warning of a potential significant air attack. Embassy staff have been instructed to shelter in place, and U.S. citizens in Ukraine are advised to be prepared for air alerts. This closure follows increased tensions with Russia, which has amassed troops near Ukraine's border. The situation escalated after the U.S. reportedly allowed Ukraine to use American long-range missiles against Russian targets. Air alerts are common in Kyiv due to ongoing drone and missile attacks from Russia. The embassy's decision reflects heightened concerns about security in the region.
