An Afghan journalist working for the BBC World Service was found dead in southern Afghanistan with a gunshot wound to the head Sunday, while insurgents elsewhere killed 15 others, including 11 police, officials said. The British Broadcasting Corp. said Abdul Samad Rohani went missing in the town of Lashkar Gar in Helmand province on Saturday. His body was found Sunday in a cemetery. Rohani was the Helmand reporter for the BBC World Service's Pashto language service, and BBC world news editor Jon Williams called his death "a terrible loss." "Rohani's courage and dedication have been a key part of the BBC's reporting from Afghanistan in recent years. His bravery - and that of his colleagues - have allowed us to tell a key story for audiences in the UK, in Afghanistan and around the world," Williams said in a statement from London.
