Hundreds of protesters gathered in Far East Russia overnight to demand a re-run of this Sunday’s local election won by a pro-Kremlin candidate and to call for the release of an anti-Putin shaman’s supporters, local media have reported.

Igor Shutenkov won 52.25% of the votes in the republic of Buryatia’s administrative center of Ulan-Ude, beating the Communist Party senator who had criticized police violence during protests in Moscow this summer. Local and regional elections took place across all of Russia’s 11 time zones Sunday.
