Multiple people were injured in two separate two-alarm fires that happened hours and blocks apart from each other in Bridgeport, officials say.

Officials say there was a total of three fires within 10 hours of each other, but that two of the fires were significant.

The first broke out at a home on Hallett Street around 9 p.m. Wednesday. 

Officials say a man and a woman inside tried to escape by jumping from the second or third floor. 

Officials say the man and woman were taken to the hospital with fractures and internal injuries.

The state fire marshal's office was called in because of the seriousness of the victims' injuries.

Investigators were on the scene into the early morning hours trying to figure out what sparked the fire when a separate two-alarm fire broke out nearby on Shelton Street.

"Our fire marshal's office and the state fire and explosive investigation unit officer went over to the third fire of the night, and actually pulled the next victim out, who has severe burns and is in Bridgeport Hospital at this time," Deputy Chief Jeff Cronin says.

All the displaced victims of the fires are being helped by the American Red Cross.
