Thousands of people, many carrying red carnations, queued on Tuesday to pay their respects to Boris Nemtsov, the Kremlin critic who was murdered last week.<br /><br /> Nemtsov rose through the political ranks during the 1990s, eventually becoming deputy prime minister under Boris Yeltsin’s rule.<br /><br /> In a gesture of conciliation from the Kremlin, Deputy Prime Minister Arkady Dvorkovich joined mourners filing into the hall where his open casket was on display. <br /><br /> Nemtsov’s coffin stood in the centre of a hall at a human rights centre named after Soviet dissident Andrei Sakharov. The casket lid was partially open to reveal his head. Photographs of the 55-year-old hung on the walls, and sombre music played.<br /><br /> Nemtsov’s mother, dressed in black, stood stooped over the coffin. His ex-wife, Yekaterina Odintsova, with a black headscarf pulled over her blonde hair, stood nearby. Nemtsov is to be buried later on Tuesday at a cemetery on the outskirts of Moscow.
