The report noted "cases of serious human rights abuses by the armed groups continued to be reported, including torture, arbitrary and incommunicado detention, summary executions, forced labour, sexual violence, as well as the destruction and illegal seizure of property may amount to crimes against humanity". The report also stated that the insurgents violated the rights of Ukrainian-speaking children because schools in rebel-controlled areas only teach in Russian. The United Nations also accused the Ukrainian Army and Ukrainian (volunteer) territorial defense battalions of human rights abuses such as illegal detention, torture and ill-treatment, noting official denials. In a 15 December 2014 press conference in Kyiv UN Assistant Secretary-General for human rights Ivan Šimonović stated that the majority of human rights violations, including executions without trial, arrests and torture, were committed in areas controlled by pro-Russian rebels.
