OVERLAND PARK, Kan. - Fire wasn't the only obstacle for Overland Park, Kan., firefighters early Tuesday.
Fire crews were called about 1:45 a.m. to the 8800 block of Westbrook Dr.
When they arrived, they found the four occupants outside of the house and a fire in the basement.
Firefighters entered, but almost immediately ran into problems as they tried to move around the home.
"Once they went in, they encountered a significant amount of hoarding, which just really makes forward progress difficult," Overland Park Fire Batallion Chief Julie Harper said.
When the fire was out in the basement, crews moved on to flames in a first-floor bedroom, but again had to fight their way through clutter.
"It slows down our progress and certainly affects our safety," Harper said.
As firefighters were putting out the flames, loud pops could be heard. It was discovered there was live ammunition in the house that was exploding.
Nobody was injured and the ammo was eventually safely removed from the home.
Authorities had to cut a hole in the front of the house to help clear debris so they could properly fight the fire.
One of the occupants was treated on the scene for minor burns.
The cause of the fire, which started in the basement and spread to the first-floor bedroom, remained unclear.
