Nationalist demonstrators in Ukraine have attacked two offices of Russian banks in the capital amid observances of the second anniversary of the protests that brought down the Russia-friendly president.

Demonstrators on Saturday threw rocks through windows at the offices of Alfa Bank and Sberbank and damaged furniture and equipment inside. Protesters also vandalized the offices of the holding company of Ukraine's richest man, Rinat Akhmetov.

Tens of thousands of people in the Ukrainian capital came to various observances of the "Day of the Heavenly Hundred." The term refers to those who died during the months of protests in Kiev that culminated with President Viktor Yanukovych fleeing.

Saturday is the second anniversary of the bloodiest day of the protests, when more than 50 people died from sniper fire.
