A roadside bomb has killed a British trooper in Helmand Province in the south of Afghanistan, Press TV reports. According to British military sources, the explosion occurred on Wednesday in the city of Nahr Seraj. Meanwhile, Taliban sources claim they have killed more than 10 foreign forces in four separate explosions in the past 24 hours. The latest fatality takes the British military’s death toll in Afghanistan to 405. Insecurity continues to rise across Afghanistan, despite the presence there of some 130,000 US-led forces. The rising number of foreign casualties has stoked opposition to the 2001-present Afghan war among the countries, which have forces deployed to the violence-torn country.
