Bulgaria and Romania are suspending all shipping on the Danube River due to severe frost and the vast amount of ice blocking the heavily traveled waterway, Bulgaria's Transport Ministry said Wednesday.Authorities say up to 90 percent of the river surface is covered with floating ice, making it extremely difficult to traverse Europe's main commercial waterway, which winds 2,860-kilometer (1,777-mile) from Germany and serves as the natural border between Bulgaria and Romania.(AP Photo/Vadim Ghirda)
