LEESBURG, Va. --
Six firefighters were hurt and four remain in the hospital after a raging house fire in Leesburg.
Crews were called to a single-family home in the 43000 block of Meadowood Court about 1 p.m. Sunday for a report of smoke in the house.
Firefighters arrived to find heavy fire and smoke. They quickly called a second alarm, bringing more manpower to the scene.
At some point, four firefighters in the house were seriously injured when conditions deteriorated and the roof toppled on them. A Mayday was called, and the firefighters bailed out.
Neighbors reported seeing firefighters jumping from the flames as the home's roof collapsed. The owner of the house was not home. She was apparently out buying flowers for the yard and returned to find the street blocked with fire trucks.
Three of the firefighters were still being treated at the MedStar burn unit at the Washington Hospital Center on Monday, News4's Megan McGrath reported. They are said to be in serious but stable condition.
Another firefighter is recovering at Inova Loudoun Hospital in Lansdowne.
The injured firefighters include men and women. Some are career firefighters, others worked with volunteer units, and the firefighters were from different stations, News4 reported.
Investigators were at the scene Monday morning, trying to determine what caused the blaze.
The Loudoun County Fire Department said people who want to make donations on the injured firefighters' behalf can do so by sending them to D.C. Firefighter Burn Foundation, P.O. Box 71056, Washington, D.C. 20024.
