US closes embassy in Kyiv over air attack warnings

The US has closed its embassy in Kyiv due to warnings of a potential air attack. Citizens in Ukraine have been advised to be ready to seek shelter. Other embassies, including those of Italy and Greece, have also closed. This closure follows Ukraine's recent use of US-supplied ATACMS missiles to strike a Russian arms depot. Russia has warned that such actions could escalate the conflict, and its officials have indicated potential retaliation against NATO countries. Tensions remain high, with Russia claiming to have shot down numerous Ukrainian drones and advancing on the ground. President Putin has also lowered the threshold for nuclear weapon use in response to perceived threats.
