During the ongoing Russo-Ukrainian War between the Ukrainian government forces and pro-Russian separatists in the Donbas region of Ukraine that began in April 2014, many international organisations and states noted a deteriorating humanitarian situation in the conflict zone. Non-governmental organisations, such as Amnesty International, also raised concerns about the behaviour of some Ukrainian volunteer battalions. Amnesty International said that they often acted like "renegade gangs", and were implicated in torture, abductions, and summary executions.
