At about :35 in this report you will see a partial collapse of the structure. Not sure if it is the same one that injured the firefighters.
Two firefighters, reported to be on ladders when walls collapsed at a house fire last night, were slightly hurt. It happened on South Minnie Street in Kansas City, Kansas. More from KSHB-TV:
When equipment arrived, flames were shooting into the air. Crews were forced to fight the fire from the exterior.
As firefighters placed ladders on the side of the house to reach the second story around midnight, the roof and walls collapsed sending flames even higher, some of them reached 50 feet into the air.
Two firefighters who were on the ladders were rushed to a local area hospital where doctors evaluated them for minor injuries.
