"This is not an isolated case": UN reacts to video of execution of Ukrainian POW

This was said in a statement by the UN Human Rights Monitoring Mission in Ukraine.

Unfortunately, this is not an uncommon case. In its latest reports, the mission documented a number of serious violations of international humanitarian law, including those committed against prisoners of war," the UN statement said.

They also stress that all criminals should be held accountable.

We shall remind you that Ukrainian President Volodymyr Zelenskyy said that the Russians had already done such things, and therefore the world should react to the atrocities. In his turn, Ukrainian ombudsman Dmytro Lubinets appealed to his international colleagues to once again show the undignified behaviour of Russians towards POWs.
