The death toll in the oil train derailment in Quebec has risen to 13, with eight more bodies discovered in the wreckage, the AP reports. Many more are still missing—the AP puts the number at "about 40," but Reuters says the figure has been updated to "around 50." The bodies found earlier are now being examined, but the coroner says it needs DNA from the families of those missing to help identify the victims, the Canadian Press reports. Canadian PM Stephen Harper visited the town of Lac-Megantic yesterday, where the derailment destroyed around 30 buildings. He described it as a "war zone" and pledged that an investigation would get to the bottom of what caused the accident, the BBC reports.
