Russia's opposition supporters carry portraits of Kremlin critic Boris Nemtsov during a march in central Moscow on March 1, 2015. Words under portraits read (L-R) "Fight", "These bullets in each of us", "He fought for our future" and "Heroes never die". The 55-year-old former first deputy prime minister under Boris Yeltsin was shot in the back several times just before midnight on February 27 as he walked across a bridge a stone's throw from the Kremlin walls.
