The European Union must remain united in its support for Ukraine and should start working on holding Russia legally accountable for its activities in the war, Latvian Prime Minister Krisjanis Karins said on his way to the second day of an EU summit.

"Russia's war is becoming ever more brutal, now blatantly aimed not only at the Ukrainian military but at Ukrainian citizens and their civilian infrastructure," Karins said on his way to a meeting of EU leaders.

"To figure out how to properly hold Russia also legally accountable for the atrocities that they are committing in Ukraine today," he said, adding that sanctions against Belarus should also be increased.
