The head-on collision of two commuter trains in southern Germany early Tuesday left 10 people dead, dozens injured and one person missing, police said, dpa reported. Eighteen people were seriously injured and another 63 sustained light wounds. The accident, which occurred near the Bavarian town of Bad Aibling at 6:50 am (0550 GMT), saw two commuter trains carrying a total of 150 people collide at full speed on a single-track line in a partially wooded area. Due to a curve in the track, the drivers had no visibility before the two trains crashed into one another, causing several compartments to derail, Transport Minister Alexander Dobrindt said in a press conference. Prosecutors said they were investigating the possibility of human error and of a technical fault.
