Munich, Rabi'II 30, 1437, February 09, 2016, SPA -- The head-on collision of two commuter trains in southern Germany that left 10 people dead and dozens injured and one remained missing was caused by "human error," a source close to the investigation told dpa of the initial findings. Who was exactly responsible for the crash was not immediately known. Eighteen people were seriously injured and another 63 sustained light wounds, police said. One missing person was believed to still be among the wreckage. Police said there was little chance of their survival. 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 had said earlier that they were investigating the possibility of human error and of a technical fault. --SPA 03:09 LOCAL TIME 00:09 GMT www.spa.gov.sa/w
