Tuesday, May 17th, 2011 — An out-of-control wildfire has burned at least half of a Canadian town of 9,800, forcing its residents to flee in a slow-moving convoy on the only highway out of town. Hundreds of buildings in the northern Alberta town of Slave Lake have been destroyed, including the town hall and police station, CNN affiliate CTV reported. No injuries have been reported. “Its extremely devastating, our loss. Its difficult to articulate,” Slave Lake Mayor Karina Pillay-Kinnee told the Globe and Mail late Sunday.
