A fire seriously damaged a four-floor apartment complex on Jean-Talon Street East Friday evening, leaving 15 people temporarily without homes.

Montreal's fire department said three residents suffered minor injuries and a firefighter was treated for heatstroke.

The building, located at 10th Avenue near St-Michel Boulevard, suffered around $125,000 in damage in the fire.

Fire officials believe the fire started in the kitchen of a first-floor apartment.
