in 11 Russian regions. Critics contend the law makes illegal holding any sort of public demonstration in favour of gay rights, speak in defence of LGBT rights, and distribute material related to LGBT culture, or to state that same-sex relationships are equal to heterosexual relationships. Also in June, parliament passed a law banning adoption of Russian children by foreign same-sex couples and by unmarried individuals from countries where marriage for same-sex couples is legal. In September, several deputies introduced a bill that would make a parent's homosexuality legal grounds for denial of parental rights. It was withdrawn later for revision. Homophobic rhetoric, including by officials, and rising homophobic violence accompanied debate about these laws. Three homophobic murders were reported in various regions of Russia in May 2013. Vigilante groups, consisting of radical nationalists, and neo-Nazis, lure men or boys to meetings, accuse them of being gay, humiliate and beat them, and post videos of the proceedings on social media. For example, in September 2013 a video showed the rape of an Uzbek migrant in Russia who was threatened with a gun and forced to say he was gay. A few investigations were launched, but have not yet resulted in effective prosecution. In a report issued on 13 April 2017, a panel of five expert advisors to the United Nations Human Rights Council—Vitit Muntarbhorn, Sètondji Roland Adjovi, Agnès Callamard, Nils Melzer and David Kaye—condemned the wave of torture and killings of gay men in Chechnya. Psychiatric institutions There are numerous cases in which people who are problematic for Russian authorities have been imprisoned in psychiatric institutions during the past several years. Little has changed in the Moscow Serbsky Institute where many prominent Soviet dissidents had been incarcerated after having been diagnosed with sluggishly progressing schizophrenia. This Institute conducts more than 2,500 court-ordered evaluations per year. When war criminal Yuri Budanov was tested there in 2002, the panel conducting the inquiry was led by Tamara Pechernikova, who had condemned the poet Natalya Gorbanevskaya in the past. Budanov was found not guilty by reason of "temporary insanity". After public outrage, he was found sane by another panel that included Georgi Morozov, the former Serbsky director who had declared many dissidents insane in the 1970s and 1980s. Serbsky Institute also made an expertise of mass poisoning of hundreds of Chechen school children by an unknown chemical substance of strong and prolonged action, which rendered
