The fire was first reported at about 4 a.m. at 8 Marie St., a vacant structure. It then spread to the three neighboring ones. The fire department worked into sunrise to get the fire under control. Officials said it was taken care of by 5:30 a.m.

Two alarms were called for a couple of hours later, when the fire department tweeted that "hot spots flared up" in two of the structures. One firefighter suffered an ankle injury.

A separate two-alarm fire on West Cottage St. displaced 12 later in the morning. The fire was first reported around 10:25 a.m. Fire officials tweeted a rescued cat was receiving oxygen and reacting positively to it.

Fire investigators determined the cause of the West Cottage St. fire to be an electrical short circuit.

The cause of early fire is still under investigation.
