A man shot and killed six people in a village near the northern Bosnian town of Tuzla on Thursday, three died in their homes and three were gunned down aboard a bus, police and witnesses at the scene said, according to Reuters. One other person was wounded in the early-morning incident in the village of Gornja Lipnica, and was taken to hospital. Initial reports said the gunman was a 45-year old from the local area, but there were no other details on his identity or motives. The Tuzla region belongs to Bosnia's Muslim-Croat federation, one of the country's two autonomous halves along with the Serb Republic. The area now hosts many thousand Bosnian Muslim refugees from other parts of the country who were displaced during the brutal 1992-95 war.
