A speeding train crashed into a bus carrying children to their kindergarten in southern Egypt today, killing about 50, officials said. Distraught families searched for signs of their loved ones along the tracks and angry villagers berated officials in the aftermath of the latest disaster to hit the country's railway system. The bus was carrying more than 50 children ages 4 to 6 when it was hit near al-Mandara village in Manfaloot district in the province of Assiut. A security official said it appeared that the railroad crossing was not closed as the train sped toward it. Egypt's railway system has a poor safety record, mostly blamed on decades of badly maintained equipment and poor management.
