More than 70,000 people marched through central Moscow on Sunday in memory of opposition leader Boris Nemtsov who was gunned down near the Kremlin in the highest-profile assassination of Vladimir Putin's rule, organisers said.
"We believe that more than 70,000 have turned up," one of the organisers, Alexander Ryklin, told AFP, adding that many people had yet to exit the underground railway network. Police estimated the crowd at more than 16,000.
