Moscow, Russia Anna Pavlikova, 18, one of two teenage girls detained on charges of involvement in extremist group ‘Novoye Velichiye’ (New Greatness), sits inside a glass-walled cage during a hearing at the Dorogomilovsky District Court. The two girls - Pavlikova and 19-year-old Maria Dubovik, who were detained in March - were part of a chat group on the Telegram messenger, which attracted up to 100 members, and called itself Novoye Velichiye. Prosecutors claim that the group was planning to topple the government and the pair, if found guilty, face up to 10 years in prison
