Almost three thousand British troops in southern Afghanistan have successfully transported a huge hydroelectric power turbine through Taleban territory. In one of their biggest operations in Helmand, a convoy of 100 vehicles took five days to move the massive sections of the turbine 180km (112 miles). The $6m (£3.4m) turbine will produce electricity for an extra 1.9m people. Prime Minister Gordon Brown said the operation was a reminder of Nato's "fundamental purpose" in Afghanistan. The operation to increase the output of the Kajaki dam in southern Afghanistan is part of a development project which has been planned for two years.
