Volodymyr Zelenskyy has released a statement rallying Ukraine's citizens on Statehood Day.
The national holiday was established by decree of Mr Zelenskyy in 2021 during the celebration of the 30th anniversary of Ukrainian independence.
The day commemorates the baptism of Kyiv, which occurred under the rule of Volodymyr the Great in 988.
Mr Zelenskyy posted a message on Telegram this morning telling citizens "there will always be Ukraine here: our history, our people, our state".
"We are fighting against a terrible enemy, one that cannot be called human and is infinitely far from true Christianity," he said.
"Its essence is ruins, and the death it brings is something we must overcome. Ukraine cannot agree to anything less than to live, to preserve itself, and to remain human.
"Ukraine will not succumb to the evil that sheds blood for its own sick self-assertion, that despises truth - both human and divine - and devalues everyone except itself. Russia builds its statehood precisely on this. But we are different."
