KELLIHER, Minn. (AP) — Authorities in northern Minnesota say about 50 people had to be rescued after ice broke up while they were fishing on Upper Red Lake and stranded them.

The Beltrami County sheriff’s office got several 911 calls Monday morning from people stranded on ice floes on the lake about 60 miles north of Bemidji.

Authorities say up to 50 people were fishing with portable ice houses on the east side of Upper Red Lake. Wind combined with the poor condition of the ice to cause cracks to widen and chunks of ice to break free.

Rescuers from several agencies along with resort owners got the stranded people off the lake.

The sheriff’s office says the ice is not safe and that people should stay off it.
