Parts of Grand Canyon National Park remained closed to the public Sunday because of wildfires and the release of chlorine gas from a North Rim water-treatment facility, the National Park Service said.

A historic lodge on the Grand Canyon's North Rim has been destroyed by a fast-moving wildfire, the park said Sunday.

Meanwhile, all of Manitoba is under a state of emergency because of the wildfires, which have led to 12,600 people evacuating their homes in the Canadian province.
