Four children were found unresponsive on the shoreline in Portneuf-sur-Mer on Quebec’s North Shore Saturday, and have been transported to a regional health clinic, Quebec provincial police said. 

The children, all above 10 years old, were among five people reported missing in a 2 a.m. 911 call. They were not breathing when they were recovered on the shore, according to police spokesperson Sgt. Catherine Bernard.

They were part of a group of 11 people fishing together when they were swept up by the tide.

“We are waiting for news about their health condition, but we fear for their lives,” she said.

Rescue teams are searching for the fifth person
