Anti-Kremlin activist and Pussy Riot member Pyotr Verzilov has been flown to Berlin for medical treatment after falling sick in a suspected poisoning.

Verzilov fell ill following an interview with Al Jazeera on the 14th of September, and has since had trouble seeing, speaking, and moving.

On their official Twitter, Pussy Riot posted a picture claiming they will punish those who poisoned Verzilov.
