Massachusetts State Police say gas lines are currently being depressurized by the company.

There were a total of 35 fires in Andover alone. All fires have been extinguished, but at peak, 18 fires were burning at the same time. At least three people have been injured in Andover, including one firefighters and at least two civilians.

Governor Charlie Baker says he communicating with safety officials. “The administration urges residents to heed instructions from local officials for important public safety announcements, including evacuations and suspending gas usage,” Gov. Baker’s spokeswoman said.

All Off-Ramps on I-495 from Exits 42 through 45 in the area are closed. On ramps remain open to allow evacuation.

The FBI says they are also investigating the explosions. “We are coordinating with our law enforcement partners as expected and personnel are on scene, as we normally would be in a situation like this to assess the situation,” the FBI said in a statement.

Lawrence Mayor Dan Rivera says the issue appears to be in the southeast part of the city.

“What we know is that there have been multiple explosions, multiple fires that are happening across the city,” Rivera told WBZ. “What we need folks to do is that if it’s happening in your home, you have a funny smell, just evacuate, come out to the street.”

WBZ-TV’s Kristina Rex says Andover Police sent out an automated phone call telling residents to evacuate their homes and turn off the gas.

North Andover Police told residents and businesses with gas service to exit their buildings until further notice.

The area is covered by Columbia for gas, but National Grid for electric. National Grid says their electric crews are responding to assist.
