Authorities in Massachusetts on Alert After Paris Attacks

Massachusetts State Police say they have taken several steps amid the attacks in Paris.

State police say they're monitoring developments with Homeland Security, and have increased security around the State House and have security in place at Logan Airport.

All active duty troopers have been asked to have an heightened awareness of suspicious activity, state police add.

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.

Others heading back home to France were desperate to make sure their loved ones were okay.

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.

For Goldstein, like so many others in France, the memories of January's Charlie Hebdo and Kosher supermarket killings were already raw.

"With the Charlie Hebdo attacks, like, people realized we were not safe. Not safe ... 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.

One Boston man left flowers with the message: We are all France. A grateful USA remembers.
