BBC Verify has so far verified footage of six incidents across Russia, including a video showing a woman throwing a petrol bomb near a St Petersburg polling station.
Other authenticated videos showed paint being poured into ballot boxes at various polling stations. In one, a woman could be seen pouring bright green liquid into a box in Moscow. Another showed a fire breaking out at a voting booth.
Russia has also enforced the vote in occupied areas of Ukraine - in the small town of Skadovsk, Russian-appointed officials said an improvised device exploded in a rubbish bin in front of a polling station, but no one was hurt.
