What is the news mainly about? [br] [originaltext] Three days of commemora

Three days of commemoration has begun in the Southern Russian town Beslan where, exactly a year ago, a school was taken over by Chechen militants armed with explosives. 331 people died in the siege. More than half of them were children. From Beslan, here is Sarah Rainsford,
     Hundreds of people filed through the ruins of School No. 1 today, survivors of the Siege alongside friends and relatives of those who died here. Many wept as they brought flowers, lit candles and left children’s toys on the charred floorboards of the school gym. One year on, the grief in Beslan is still raw. But many here are also extremely angry with the authorities. They are furious, no senior officials have been held to account for the fact that the government ever made it to the school, for the decision not to negotiate, and then for the violent way the 3-day siege eventually ended.
