US Embassy in Kyiv Closes Amid Rising Russian Air Attack Threats

The U.S. has closed its embassy in Kyiv, citing specific intelligence of a potential significant air attack amid escalating tensions with Russia. The closure follows reports of Ukraine using U.S.-made long-range missiles against Russian targets, which Russia condemned as an escalation. In response, Russia has updated its nuclear doctrine, allowing for nuclear weapon use if attacked by a non-nuclear state supported by a nuclear power, highlighting the growing geopolitical strain.
