They note that earlier, the Estonian State Court did not take into consideration an appeal filed by Polyakov. According to a charge filed in Estonia, the suspect, 34-year-old Polyakov, was a member of a terrorist group. According to the state prosecutor’s office, he fought in and around Luhansk city against Ukrainian troops since June 2014. According to media, Polyakov might have been a witness in capturing Ukraine’s military pilot Nadiya Savchenko, who was exchanged in May for two Russians after being held in Russia for two years.
