Are war crimes being committed by Russia in Ukraine? -

Ukraine President Volodymyr Zelensky has accused Russian President Vladimir Putin of war crimes, following an attack in the country's second largest city, Kharkiv.

Russian missiles and rockets have hit the cultural heart of the city, where an opera house, concert hall and government offices were struck in Freedom Square.

Russia has previously denied targeting residential areas, but the International Criminal Court - which examines war crimes - is looking to open an investigation.
