The western Canadian province of Alberta declared a state of emergency on Saturday after a hundred wildfires broke out and drove some 25,000 residents from their homes. Authorities have asked thousands more to be ready to leave at any time.
A total of 110 fires, fanned by strong winds, have been recorded, a third of which are out of control. The province, one of the largest oil producers in the world, "has experienced a hot and dry spring and with so much small wood, it only takes a few sparks to start some really scary fires"
