Mourners surround a coffin as they attend a memorial service before the funeral of Russian leading opposition figure Boris Nemtsov in Moscow, March 3, 2015. Several hundred 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.
