CALGARY, Alberta, Ramadan 10, 1437, June 15, 2016, SPA -- The Fort McMurray wildfire in northern Alberta that forced the evacuation of 90,000 residents and shut in more than a million barrels per day of oil output was most likely caused by human activity, the Royal Canadian Mounted Police said on Tuesday, according to Reuters. The RCMP appealed for public assistance in determining how the fire started and whether a criminal offence was involved. --SPA 00:44 LOCAL TIME 21:44 GMT www.spa.gov.sa/w
