Ukrainian parliament on Sunday banned the symbols “Z” and “V”, that are used by Russia’s military to promote its war in Ukraine and agreed to President Volodymyr Zelensky’s call to allow their use for educational or historic purposes.

Yaroslav Zheleznyak, an opposition member, announced the decision on the Telegram messaging app, saying 313 deputies had voted in favour in the 423-member Verkhovna Rada assembly.
