Russia protests put pressure on Vladimir Putin
Thousands of people have attended the biggest anti-government rally in the Russian capital Moscow since the fall of the Soviet Union, with smaller protests staged in St Petersburg and other cities.
The demonstrators wanted to voice their concerns about allegations of ballot-rigging in the recent parliamentary elections, with many demanding a re-run of the vote.
