Bad Aibling, Rabi'II 30, 1437, Feb 9, 2016, SPA -- Two commuter trains crashed head-on Tuesday morning in southern Germany, killing at least nine people and injuring around 150, slamming into each other on a curve without braking after an automatic safety system apparently failed to stop them, the transport minister said. The first rescue units were on the scene within three minutes of receiving emergency calls, but with a river on one side and a forest on the other, it took hours to reach some of the injured in the wreckage. Rescue crews using helicopters and small boats shuttled injured passengers to the other side of the Mangfall river to waiting ambulances. Authorities said they were taken to hospitals across southern Bavaria, AP reported. "This is the biggest accident we have had in years in this region and we have many emergency doctors, ambulances and helicopters on the scene," police spokesman Stefan Sonntag said. --SPA 19:40 LOCAL TIME 16:40 GMT www.spa.gov.sa/w
