Parliament also voted to label militant groups in the east terrorist organisations
Ukraine's parliament has voted to designate Russia an aggressor state and has called on the international community to do the same.
A statement read: "Parliament recognises the Russian Federation as undertaking state aggression against Ukraine and calls on Ukraine's international partners to not provide for impunity for those responsible for crimes against humanity committed since the beginning of Russian aggression against Ukraine."
The Ukrainian parliament also passed a motion declaring the so-called Luhansk and Donetsk People's Republics terrorist organisations. It said that the militant groups controlling parts of Ukraine's eastern Donbas region have committed terrorist acts against civilians.
The vote comes following a deadly rocket attack that left 30 dead and 100 others injured in the Ukraine-held port city of Mariupol.
Ukrainian officials say they hope other countries will label the militant groups terrorist organisations and recognise Russia's role as an aggressor toward Ukraine.
US President Barack Obama said earlier this week during his visit to India that the US could tighten sanctions against Russia, although he has ruled out US military involvement in the conflict.
