Russians are at the polls to elect seats in the State Duma, the lower house of Russia's parliament.

Jailed Kremlin critic Alexei Navalny's "Smart Voting" bot has disappeared from the Telegram messenger app following similar moves by Apple and Google on Friday at the start of the three-day parliamentary vote.
