Evacuees who were stranded in mining camps north of the Canadian oil town of Fort McMurray began a daunting escape Friday from the fire-ravaged area in the Canadian province of Alberta, according to dpa. The evacuees were accompanied by police escorts on the ground and military helicopters in the air as they fled for the second time in three days. Authorities wanted the evacuees moved out of the camps in the remote area because they were not designed to accommodate the estimated 25,000 people who had fled there
