Some 5,000 people, many of them elderly, gathered in the center of the Pacific coast city of Vladivostok, to denounce recent government reforms, which hiked rates for gas, electricity, and rent.
Hundreds also protested in Khabarovsk, another Far Eastern city, and around 1,000 in the Siberian city of Omsk.
Household bills have soared in Russia as the government moves to introduce market prices and end state subsidies.
