In the report, Amnesty International looks into the repressive tactics employed by the Russian authorities against the Crimean Tatar community and other dissenting voices in the two and a half years they have been in control the Crimean peninsula.
"As the most visible and cohesive group in Crimea opposed to the Russian occupation, the Crimean Tatar people have been deliberately targeted by the de facto local and Russian authorities in a wave of repression aimed at silencing their dissent and ensuring the submission of every person in Crimea to the annexation," said John Dalhuisen, Director of Amnesty International's Europe and Central Asia Programme.
"Through the adoption wholesale of the repressive Russian legal framework in Crimea, which was in itself a violation of international law, the Russian authorities have prosecuted and forced into exile virtually all dissenting voices, including key leaders and activists within the Crimean Tatar community."
"As well as being used as a tool against the Crimean Tatar minority, this legal framework has had disastrous consequences more generally for freedom of assembly and a free media in Crimea."

Several of these individuals' cases are documented in the report. The Crimean Tatar's principle representative organization, the Mejlis, has also been banned arbitrarily as an "extremist organization" and any association with it criminalized.
"However popular Crimea's annexation may be with many on the peninsula, there is no escaping the fact that it has come at a very high price indeed for those that oppose it," said John Dalhuisen.
"All restrictions on the Mejlis must be lifted, and criminal proceedings designed to harass and intimidate its members, and others that peacefully oppose the Russian occupation and annexation should cease."
Even before the Mejlis was outlawed, the de facto local and Russian authorities were pursuing prominent figures from the organization. Its leader, Refat Chubarov was forcibly exiled from Crimea, as was his predecessor, Mustafa Dzhemilev, a Crimean Tatar veteran human rights activist and vocal opponent of the occupation. Following the banning of the Mejlis, the authorities turned their attention to the remaining senior members of the organization still in Crimea, including deputy leader Ilmi Umerov.
After appearing in a TV interview in which he insisted that Russia should leave Crimea, Ilmi Umerov was taken for questioning by officials from the Russian Federal Security Service. He was informed he was being investigated for "threatening the territorial sovereignty of the Russian Federation."
After several months under investigation, he was forcibly confined to a psychiatric institution and for the purpose of a "psychiatric examination" was placed in a closed ward for patients with severe conditions.
Another deputy leader, Akhtem Chiygoz, was arrested in January 2015, accused of having organized "mass disturbances" following street clashes between pro-Ukrainian and pro-Russian supporters in February 2014. According to media footage and eyewitness accounts, he was one of those attempting to keep the crowds apart to prevent violence. After spending more than 15 months in detention, his trial began in August. He has not been allowed to attend the court in person, participating instead via a poor Skype connection, meaning he cannot hear all that is being said in the courtroom or consult with his lawyer in private. His trial is ongoing.
Ervin Ibragimov, a Crimean Tatar activist, disappeared on 24 May. He had been part of an organization aimed at promoting the rights of Crimean Tatars and their cultural heritage following Crimea's annexation. Shortly before he went missing, he had told friends he was being followed.
Russia has also used its anti-terror legislation to target ethnic Crimean Tatars. Nineteen men, including human rights defender Emir-Usein Kuku, have been arrested and faced prosecution on charges of being members of the proscribed terrorist group, Hizb ut-Tahrir. Amnesty International believes the charges against him and quite possibly others, to be unfounded.
"The cases documented in this report demonstrate the ruthlessness of the Russian authorities in brooking absolutely no dissent to their rule in Crimea," said John Dalhuisen.
"The international community may have few tools to address the underlying politics, but it must speak up for those being bullied and harassed into silence."
