Ukraine celebrates its 31st anniversary of independence from the Soviet Union on Wednesday, exactly half a year after the war began.
President Volodymyr Zelensky warned that Russia may mark the occasion with an increase in attacks.
The warning itself is not new.
A month before the war began, on January 24, US citizens were told to leave the country.
In July, the US issued a further warning about heavy missile attacks.
The State Department has also had a travel warning for Ukraine in place since February.
