CAMP BASTION (AFP) - The British government is to announce Tuesday a 245-million dollar programme to combat the threat that roadside bombs pose to troops in Afghanistan, an official said. A government official passed details of the programme to reporters accompanying Prime Minister Gordon Brown on Sunday to Afghanistan, where he met President Hamid Karzai, British troops and Afghan soldiers undergoing training. This year has been the bloodiest for British forces since the 1982 Falklands War. Around 80 percent of the soldiers who are killed die because of improvised explosive devices (IEDS), many of which explode as they travel by road. The 150 million pounds will be spent over three years and has been reprioritised within the defence budget as part of a wider Afghanistan support package to be announced in parliament on Tuesday. It includes 50 million pounds in the first year to fund new facilities for counter-IED training in Britain and a new analysis centre to examine material collected from surveillance, the official added. In addition, an extra 10 million pounds will be approved from reserves for 400 new state-of-the-art hand-held mine detectors. Brown saw the detectors in action when he watched trainers putting Afghan soldier recruits through their paces in the southern province of Helmand, which is where Britains troops are based and is one of the bloodiest battlefields in the war. So far this year, 100 British troops have been killed in Afghanistan and 237 have been killed overall since the October 2001 US-led invasion to oust the Taliban regime. Browns government has faced controversy over claims that British troops are dying needlessly because they lack vital equipment like helicopters.
