LONDON - British Muslims are actively taking part in war against the British forces by providing the Taliban with electronic devices to make roadside bombs for use in attacks against British forces serving in southern Afghanistan, The Telegraph has reported. The devices, which enable Taliban fighters to detonate roadside bombs by remote control, are either sent to sympathisers in the region, or carried by volunteers who fly to Pakistan and then make their way across the border. Details of how British electronic components have been found in roadside bombs were given to David Miliband, the Foreign Secretary, when he visited British troops at their military compound at Lashkagar, in Helmand province, earlier this week. In a briefing on British operations in southern Afghanistan by Brigadier Gordon Messenger, the Royal Marine commander of the British battlegroup, Mr Miliband was shown examples of the crude, homemade devices that are being used in attacks against British patrols. They included mobile phones filled with explosives, which could kill or seriously injure UK soldiers patrolling on foot, and more sophisticated devices that can be used against military vehicles. Explosives experts who have examined the devices say they have found British-made electronic components that enable Taliban insurgents to detonate their home-made, roadside bombs by remote control. The electronic devices smuggled into Afghanistan from Britain range from basic remote control units that are normally used to fly model airplanes to more advanced components, enable insurgents to conduct attacks from up to a mile away from British patrols. "We have found electronic components in devices used to target British troops that originally come from Britain," a British explosives officer told Miliband during a detailed briefing on the type of improvised explosive device (IED) used against British forces. When asked how the components had reached Afghanistan, the officer explained that they had either been sent from Britain, or physically brought to Afghanistan by British Muslims who had flown over. The disclosure is the latest in a string of suggestions from British commanders about the connections between British Muslims and violence in Afghanistan. In August, Brigadier Ed Butler, the former commander of UK forces in Afghanistan said that there are "British passport holders" in the Taliban ranks. Other officers believe their soldiers have killed British Muslims fighting alongside the Taliban. And last year, it was revealed that RAF Nimrod surveillance planes monitoring Taliban radio signals in Afghanistan had heard militants speaking with Yorkshire and Midlands accents British commanders have recorded a significant rise in the use of IEDs during the past two years, partly the result of the success British forces have recorded in defeating the Taliban in conventional attacks. British officials are expected to come under pressure from US President Barack Obama to add to the 8,300 British service personnel currently serving in Afghanistan as Washington prepares to undertake a military surge similar to the one that was so successful in Iraq.
