ST. LOUIS -- Firefighters saved four people stranded on the Mississippi River in south St. Louis County after their boat lost power, according to KSDK-TV.

Firefighters said the boat hit a buoy and lost power and lights Sunday night at a spot where the Meramec River flows into the Mississippi.

Rescuers were concerned the vessel could be hit by barge traffic so they took a boat onto the river to rescue them.

One boater, whose name was not released, was taken to a hospital for a minor back injury.
