US closes embassy in Kyiv over potential air attack threat

The US closed its embassy in Kyiv on November 20 due to specific information about a potential air attack. Embassy staff have been instructed to shelter in place, and US citizens in Ukraine are advised to prepare for emergencies. This decision follows Ukraine's recent use of US-made ATACMS missiles to strike targets in Russia. The US had lifted restrictions on these missiles, allowing Ukraine to enhance its defense capabilities amid ongoing conflict. In response to Ukraine's actions, Russia has revised its nuclear policy, expanding the conditions under which it might use nuclear weapons. Moscow has warned that Western support for Ukraine could lead to direct involvement in the conflict.
