A farm fire killed hundreds of young cows overnight, north of St. Hyacinthe.

The fire started around 11:30 p.m. Monday in two barns on Rang Bourgchemin Ouest in Saint Hugues.

When firefighters arrived the barns were engulfed in flames, and by 1 a.m. nothing was left except for charred wreckage as the buildings collapsed.

About 300 calves died in the flames.

The cause of the fire is unknown.
