Ukrainian President Zelensky has repeatedly reaffirmed his will to fight back decisively without yielding to Russian aggression.



The Russian military had previously issued an ultimatum to surrender and leave Mariupol by 6 pm yesterday (21st) our time, but this was officially rejected.



"Russia wants to hand over Kharkiv, Mariupol and the capital Kiiu," Zelensky said in an interview with the local media.



Ukraine's government has claimed that 150 children have been killed and more than 400 schools and 110 hospitals destroyed since the invasion of Russia. 



He also accused Russia of committing a “national terrorism”.



[Lesnikov / Ukrainian Defense Minister: This is 'national terrorism'.

We're going to do more terrorism, so we need to stop Russia.

It can even attack other countries.]



Meanwhile, the Russian Foreign Ministry summoned the US ambassador to Russia, and on the 16th, US President Biden called Putin a 'war criminal'.



Russia's foreign ministry said, "The US president's remarks put Russia-US relations on the brink of severance."



President Biden later issued a statement urging Russia to prepare for a malicious cyberattack.
