Tens of thousands of demonstrators cheered opposition leaders and jeered the Kremlin in the biggest show of outrage yet against Prime Minister Vladimir Putin's 12-year rule. The Moscow demonstration was even bigger than a similar rally two weeks ago, signaling that the protest movement ignited by the tainted Dec. 4 parliamentary election may be growing. Protest were also held in dozens of other cities and towns across Russia. Rally participants densely packed a broad avenue, which has room for nearly 100,000 people, about some 1.5 miles from the Kremlin, as the temperature dipped well below freezing. They chanted "Russia without Putin!" The police reported that 28,000 people participated in the demonstration, but rally organisers said the true number was around 120,000. The journalists of the Novaya Gazeta, who counted participants at the entrance to the demonstration site, estimate the number at 102,000.
