The US embassy in the Ukrainian capital Kiev closed its doors on Wednesday and issued an urgent warning to staff to take cover, citing information that Russia was planning a ‘major air attack’.
The US Embassy in Kiev has received specific information about a possible major Russian air strike on November 20,’ the US Embassy in Kiev said in a statement. The embassy will be closed and recommends that US citizens prepare to evacuate immediately in the event of an air alert.

The unusual warning comes after Ukraine used US-made ballistic missiles to target Russian territory for the first time, a day after US President Joe Biden lifted restrictions on their use.
