The latest news from around the state
Meanwhile in Boston, police say patrols have been stepped up around the French consulate and more officers are present at Friday night's Boston Celtics game at TD Garden.
However, both state and Boston police say there are no specific or credible threats to security in the area at this time.
Dozens have been killed in a series of attacks in and around the French capital Friday night.
A state of emergency has been declared in France, and its borders have been ordered closed.
At Boston's Logan Airport, passengers arriving in the U.S. from France say they are shocked and upset after learning about the attacks.
"I just heard there's been an attack on my city, and they actually killed people in so many places. That's terrible. I'm very shocked," Parisian Francois Planquette said with tears in his eyes.
New Hampshire resident Charlotte Ford says when they left Charles DeGaulle International Airport, she found it odd that they were bussed out to the tarmac.
"There were security people in the plane, but they weren't saying what was going on," she said.

Flights to Paris were still leaving Logan on Friday night, despite orders to close all French borders.
College students Nina Goldstein and Gabrielle Larnaudie Eiffel were visiting Boston Friday, and as news of the horrifying terrorist attacks in Paris spread, they felt called to offer a tribute: white roses outside the offices of the French Consulate on Stuart Street.

It just seems like a few months ago that Parisians [finally] don't feel like on the streets of Paris they're afraid to be attacked. And now it's happened again. In less than one year. So it's just crazy," she said.
