LONDON (AFP) - A British soldier has died from wounds sustained in an explosion in southern Afghanistan last month, the Ministry of Defence said Tuesday. The soldier from the 1st Battalion The Royal Anglian Regiment died in Selly Oak military hospital in Birmingham on Monday, following an explosion in the Musa Qalah District of Helmand Province on Feb 21, it said. It is with sadness I must inform you that one of our comrades succumbed to his wounds last night in Selly Oak Hospital, said a spokesman, adding that the death was not linked to the recent Operation Mushtarak offensive. The explosion happened while he was on a patrol to the north of Musa Qalah district centre, part of the ongoing successful operations in the... area to drive the insurgents away from the local people and away from the district centre. The death is the 28th this year and brings to 273 the number of British troops killed since operations in Afghanistan began in October 2001. Of these, at least 240 were killed as a result of hostile action, according to the MoD. Britain has around 10,000 troops in Afghanistan, largely battling Taliban militants in Helmand.
