"Russian-backed separatists in Donbas engaged in abductions, torture, and unlawful detention, employed child soldiers, stifled dissent, and restricted humanitarian aid," the report reads.
More than 9,750 people have been killed since fighting broke out in eastern Ukraine in March 2014 between the Russia-backed separatists and Ukrainian government forces.
On the Kyiv government, the U.S. State Department report says there are problems within the Ukrainian judicial system that are impairing human rights. "The government generally failed to take adequate steps to prosecute or punish most officials who committed abuses, resulting in a climate of impunity," the report reads.
According to the report, abuses by government forces were also reported.
"Credible observers attributed thousands of civilian deaths and injuries, as well as widespread abuses, to Russian-backed separatists in Ukraine's Donbas region, and to Russian occupation authorities in Crimea," the report reads.
It also cites politically motivated arrests, detentions, and trials of Ukrainian citizens in Russia. "Authorities especially targeted individuals and organizations that professed support for the government of Ukraine or opposed the Russian government's activities in Ukraine," the report reads.
