Authorities in northeastern Austria say torrential rains have caused widespread flooding that has left hundreds of homes under water and knocked out train services. Officials say the flooding is most acute in the town of St. Poelten, about 50 miles (80 kilometers) west of Vienna in the province of Lower Austria. The easternmost province of Burgenland also was flooded. Officials say the Danube is dangerously high and some tributaries have overflowed. Austria's national railway says train service was suspended in parts of the stricken region Monday because tracks are submerged. Officials said some highways also were impassable. Firefighters were reinforcing river banks with sandbags.
