A grizzly bear attacked a group of students and teachers on Thursday in a remote community on British Columbia's Central Coast, injuring several people, according to the school, police and conservation officials.

The incident occurred in the Bella Coola Valley of the Nuxalk Nation.

CBS News' Canadian partner CBC reported two people were critically injured and two others were seriously hurt. Others were treated on the scene and released.

The Royal Canadian Mounted Police confirmed to CBS News that they responded to a call at 1:35 p.m. Thursday about a grizzly bear attack in an area called Old Trail, but did not provide any further information about the victims. CBS News also reached out to the British Columbia emergency service but did not receive a response.
