Port Authority police are on a heightened alert at the New York-New Jersey crossings, as well as area airports and seaports in the wake of Friday's mass-casualty terror attacks in Paris, according to a report by New Jersey Advance Media.

It quoted police spokesman Joe Pentangelo saying that meant increased patrols and checks of backs, buses, trucks and trains. The report said United Airlines had not suspended flights from Newark to Paris despite a declaration France's borders would be closed. It also said the Transportation Security Administration declined to comment on any special security measures.

Around 7:30 p.m., New Jersey State Police told New Jersey 101.5 that while they were closely monitoring events in Paris, they were operating with normal procedures — though Gov. Chris Christie, in a Tweet Friday night, said "Ww are working with our Homeland Security Dept and NJ State Police to make sure that all steps are taken to protect NJ after Paris attacks."

Across the Hudson, New York City police said officers have been deployed to sites across the city, including French government buildings. But they said there is no indication the attack has any link to New York City.
