Baltimore fire officials are busy trying to figure out what caused three fires in the city Tuesday.
Crews were called to two separate fires only minutes apart.
A row home in the 200 block of Mount Holly Street caught fire shortly after 11 a.m.
The corner home was occupied, and one firefighter suffered a minor burn injury and was taken to the hospital.
Then on the other side of town, a vacant house fire in east Baltimore on North Milton Avenue caught fire. Crews were able to control the fire in about 50 minutes.
No one was hurt.
Earlier Tuesday morning, a vacant house fire in downtown Baltimore also caught fire.
