A small group of advocates for Alexei Navalny congregated in St. Petersburg on Thursday (August 20) to show support.

Footage shows a couple of supporters bearing placards of the opposition politician's face, as they're surrounded by the press on Nevsky Avenue.

Navalny became unconscious on a flight from Siberia to Moscow, forcing it to make an emergency landing in Omsk.

Many have claimed that he has been poisoned due to his political beliefs, including his lawyer.
