Emergency crews responded to a three-alarm building fire in Pittsburgh's Larimer neighborhood Tuesday.
The fire was reported around 6:30 p.m. at a vacant building on the 500 block of Winfield Street.
Investigators said there were no reported injuries.
The blaze happened across the street from a fire Monday night, which also involved a vacant house.
"We do not know if these are connected fires in any way, but all of that is under investigation," said Sonya Toler, public information officer for Pittsburgh police.
A Channel 11 crew at the scene reported the fire was under control shortly after 7 p.m.
