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

The U.S. has closed its embassy in Kyiv due to a warning of a potential significant air attack from Russia on November 20. Embassy staff have been instructed to shelter in place. This warning follows Ukraine's recent use of U.S.-made ATACMS missiles to strike deep into Russian territory. The situation escalated after Russian President Vladimir Putin indicated a lower nuclear threshold. The embassy closure marks a shift in U.S. operations in Ukraine amid rising tensions and military actions between the two countries.
