US embassy in Kyiv closes due to warning of potential air attack

The U.S. embassy in Kyiv will close due to a warning of a potential air attack on Wednesday. Embassy staff have been instructed to shelter in place, and U.S. citizens are advised to be ready to do the same. This closure follows Ukraine's recent use of U.S. ATACMS missiles against Russian targets, marking a significant escalation in the conflict. Russia has warned that such actions could lead to direct involvement from NATO countries. Tensions have increased, with Russian President Vladimir Putin recently lowering the threshold for nuclear strikes in response to conventional attacks. This situation reflects the highest tensions between Russia and the West in decades.
