New York Gov. Andrew Cuomo and New Jersey Gov. Chris Christie announced coordinated security efforts between their states, citing growing terrorist threats.

Following an event in Manhattan, Cuomo called the Islamic State a "metastasizing problem" and said "the threat was have today is much worse than the threat we had 13 years ago."

"They have more resources, they have more sophistication, they have Europeans with European passports who can just get on a plane," he said.

The governors said they would meet with the FBI Joint Terrorism Task Force, as would local and state representatives including the New York Police Department and the Port Authority of New York and New Jersey, said the Washington Post.

The meeting will also include George Venizelos, assistant director in charge of the FBI's New York Field Office. Jeh Johnson, U.S. secretary of homeland security, has been invited to attend.

"Bringing these groups together will help strengthen the existing efforts of men and women who are charged with the protection and security of our region, and ensure that any potential threat continues to be effectively responded to," Christie said.

Efforts will include securing “high-risk entry points” such as airports, ports, and rail in the region.
