File photograph: William Campbell/New York TimesEleven people were injured, two of them critically, when a grizzly bear attacked a group of schoolchildren and teachers on a walking trail in British Columbia, Canada. The Nuxalk Nation said the “aggressive bear” remained on the loose and police and conservation officers were on the scene. “We are devastated for the individuals and families impacted by the bear incident,” Nuxalk Nation chief Samuel Schooner said in a statement. Grizzlies, which have coexisted with the Nuxalk Nation for generations, have a deep cultural significance for many of the First Nations along the Pacific coast.
