An anti-Kremlin activist lost his sight, hearing and ability to walk in a suspected poisoning last week but is doing better since he arrived in Berlin for treatment, two friends said Sunday.

Pyotr Verzilov, publisher of a Russian online news outlet and affiliated with the anti-Kremlin band Pussy Riot, arrived in Berlin from Moscow late Saturday on a medical transport plane, the managing director of the Berlin-based Cinema for Peace human rights group, Jaka Bizilj, said. The group paid for the transport, and Bizilj said that Russia had been ¡°cooperative¡± in the matter.

Photographs taken by Bizilj at Berlin¡¯s Schoenefeld airport showed Verzilov on a stretcher, his eyes closed, as he was being transferred to an ambulance.
