Fire crews in Montgomery County were fighting a two-alarm house fire in Bridgeport early Sunday morning that they say injured at least two people.

They were called to the area of Grove and Rambo streets just before 3 a.m., where they saw flames spread to multiple rowhomes.

We're hearing reports of multiple people trapped on their roofs. Firefighters and neighbors needed to help them escape. 

We don't know the conditions of those who were injured.
