CALGARY, Alberta — Rescue crews, police and paramedics rushed to the remote Canadian Rocky Mountain region of Banff National Park late Thursday after receiving reports that a group of hikers were hit by a rockslide, causing possible injuries and deaths.

“The initial report indicated there were multiple hikers and there may be serious injuries and/or fatalities,” Royal Canadian Mounted Police Cpl. Gina Slaney said in a news release.

Parks Canada said in a statement that it is responding to a report of “a serious rockfall incident with involvement near Bow Glacier Falls in Banff National Park.”

The site is north of Lake Louise on the Icefields Parkway, about 124 miles northwest of Calgary.

Temporary road closures were expected on the Icefields Parkway near Bow Lake in order to allow responders to work. Parks Canada has asked visitors to avoid the area.

STARS Air Ambulance spokeswoman Kate Langille said two of its units were deployed around 2 p.m.
