A wildfire on Alaska’s Kenai Peninsula south of Anchorage expanded in size Sunday, leading officials to issue a mandatory evacuation order for 1,000 structures. The number of people told to flee their homes isn’t clear, said Michelle Weston, spokeswoman with the Alaska Interagency Management Team, which includes the state Division of Forestry and federal and local officials. Officials said that as of 4 p.m. Alaska time, the fire covered nearly 243 square miles and may continue to grow as it burns in the 1.9 million-acre Kenai National Wildlife Refuge.
