Fury over delays in the rail network in Argentina has boiled over triggering rioting and wide scale destruction at a suburban train station in Buenos Aires. Mobs went on the rampage for about five hours, setting fire to a train station and carriages and fighting with police in some of the worst violence the capital has seen in years.The rioting broke out after passengers staged a protest over delays in the service. The country’s Interior Minister Anibal Fernandez has blamed what he called leftist and union groups: “They can be angry, and one can understand it but no resident anywhere in the world sets fire to a train station or sets fire to a train. This was planned.” More than 80 people were arrested in the violence that comes days before a 34 nation summit of the Americas. US President George W. Bush is to attend – protests at his visit are expected.
