Mourners, including Mikhail Kasyanov (L), an opposition leader and former Russian prime minister, lay flowers at the grave of Russian leading opposition figure Boris Nemtsov during his funeral in Moscow, March 3, 2015. Thousands of Russians, many carrying red carnations, queued on Tuesday to pay their respects to Nemtsov, the Kremlin critic whose murder last week showed the hazards of speaking out against Russian President Vladimir Putin.
