KABUL (Afghanistan) - British Prime Minister David Cameron says British troops may start withdrawing from Afghanistan next year. Cameron spoke during a surprise trip to Afghanistan on Tuesday. At the NATO summit in Lisbon last month, Cameron said British troops will quit their combat role in Afghanistan by 2015. Also Tuesday, Cameron urged an investigation into the death of a British soldier in a friendly fire incident in the country's south. The British Defense Ministry has said a British soldier who died in southern Afghanistan on Sunday may have been killed by supporting fire from a US aircraft. He was shot while on patrol in Nad Ali district of Helmand province. He was the 346th death among British forces and civilian defense workers in Afghanistan since 2002.

"Well, it's absolutely tragic when incidents like this happen and my heart goes out to the family concerned - to lose the loved one and to lose the loved one in this way is obviously a terrible thing," he said in the southern Helmand province.
