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.
