WINNIPEG -- Fire crews in southern Manitoba are working to extinguish a wildfire estimated to be about 400 acres in size. Stuartburn Fire Chief Bob Fosty told CTV News the fire was reported around 2:30 p.m. on Monday. It is burning roughly seven kilometres southwest of Zhoda -- though Fosty said its origins are unclear at this time. While fire crews do not yet have the fire under control as it spreads out towards the east and west, Fosty said there have been no evacuations required. "There has been no injuries or loss of life or loss of property, but we are working at it to extinguish both the east and the west edge of it."
