Bucha satellite image contradicts Russian claims
Does video show Russian prisoners being shot?
Last month President Zelensky promised to find the Russian soldiers who apparently shot dead an unarmed Ukrainian prisoner of war named Oleksandr Matsiyevskiy.
EU foreign affairs spokeswoman Nabila Massrali reminded Russia it had to abide by humanitarian law and added that the EU was committed to holding to account all perpetrators of war crimes committed during the war.
