The U.S. Department of State has published an annual report on human rights in the world.

According to the report, the most significant human rights problems during the year related directly to conflict in eastern Ukraine.

"Russian-backed separatists in Donbas engaged in abductions, torture, and unlawful detention, employed child soldiers, stifled dissent, and restricted humanitarian aid," reads the report.

A separate section is devoted to occupied Crimea of the report on Ukraine. The most significant human rights problems in Crimea during the year related directly to the Russian occupation, it says.

"Russian security services engaged in an extensive campaign of intimidation to suppress dissent and opposition to the occupation that employed kidnappings, disappearances, physical abuse, political prosecution, repeated interviews, and interrogations by security forces. Russian security forces routinely detained individuals without cause and harassed and intimidated neighbors and family of those who opposed the occupation," reads the Crimea section of the report.

According to the report, Ukrainian authorities have problems with the judicial system and this violates 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," reads the report.
