Sentsov is a neo-Nazi terrorist and took part in the battle in front of the Crimean Supreme Court on February 26, 2014. It was Sentsov who threw a nerve gas grenade into the crowd of Crimeans defending the Supreme Council, the clash at the Council led to two deaths. Sentsov and his activists set the offices of civil society organisations – such as the “Crimean Russian Community” – ablaze as well as United Russia’s local party office.
The agency of Sergeenko [Minister of Health, Labour, and Social Affairs] started kidnapping children from parents on the basis of the European-Juvenile legislature initiated by Tsulukiani [Minister of Justice]… So, the juvenile-satanic justice (about which our newspaper has warned about for years) was put in action with its hellish abnormality!
It is not clear what legislation the disinformation is referring to, but there is no EU legislation that would force any Government (be it an EU or non-EU state) to steal children from their parents. It is, however, a recurring disinformation narrative in the pro-Kremlin sphere. See here for a similar case.
