Thousands of protesters have gathered in downtown Moscow to demonstrate against what they describe as a "fascist coup" one year ago in neighboring Ukraine.

The demonstrators gathered near Red Square on Saturday to protest events in Ukraine, where a pro-European protest movement last year led to the ouster of the country's Russia-leaning president on Feb. 21.

The protesters included ultranationalist bikers, pensioners, war veterans, student organizations and other pro-government groups. Many waved Russian flags, others bore banners that said: "Die, America!"

Police said that 35,000 people attended, though those numbers were impossible to verify independently.

Anti-Western sentiment in Russia, in part spurred by state television coverage of the Ukraine crisis, has spiraled to new heights.
