Four people were sent to the hospital, two of them with serious injuries, following an early Wednesday morning house fire in Watertown.
The fire was in a two story home at 525 3rd Street Southwest.
Adam Heinrich is a lieutenant with Watertown Fire Rescue. He says it happened shortly after midnight. Heinrich says the adults rescued the three children, ages 5, 7 and 13.
Heinrich says the fire rekindled on the second floor of the home early Wednesday morning, sending crews back to the home.
The cause of the fire is under investigation.
