A British soldier was killed and two more were injured when their vehicle was hit by an explosion in southern Afghanistan Tuesday, the military said. The soldier, a member of a reconnaissance brigade in the 5 Regiment Royal Artillery, was conducting a tactical patrol north of Sangin, in Afghanistan's violence-wracked Helmand Province, when his vehicle was caught in an explosion just after 1 p.m. local time, Britain's Ministry of Defense said in a statement. He was evacuated to a field hospital but medics were unable to save his life. Two more soldiers were wounded in the incident, but their injuries were not thought to be life threatening, the military said. It added that next of kin had been informed.
