MOSCOW -- Boris Nemtsov, a charismatic Russian opposition leader and sharp critic of President Vladimir Putin, was gunned down Saturday near the Kremlin, just a day before a planned protest against the government.
The death of Nemtsov, a 55-year-old former deputy prime minister, ignited a fury among opposition figures who assailed the Kremlin for creating an atmosphere of intolerance of any dissent and called the killing an assassination. Putin quickly offered his condolences and called the murder a provocation.
