People hold flags and posters during march to commemorate Kremlin critic Nemtsov in central Moscow

People hold flags and posters during a march to commemorate Kremlin critic Boris Nemtsov, who was shot dead on Friday night, in central Moscow March 1, 2015. Holding placards declaring “I am not afraid”, thousands of Russians marched in Moscow on Sunday in memory of Nemtsov, whose murder has widened a split in society that some say could threaten Russia’s future.
