Pristina - A man believed to be an ethnic Albanian shot and killed three Serbs, including a four-year-old child, and seriously wounded two others in an ethnically mixed village in Kosovo. The gunman opened fire late on Sunday on a group of Serbs outside a shop in Cernica, a village in Kosovo's south-east, Capt Russell Berg of NATO said. It was the worst in a series of recent attacks on Serbs in Kosovo. The boy's uncle and a 60-year-old man were also shot dead. Two men aged between 25 and 35 were seriously wounded.
