Terrorism scare as fishermen spotted near JFK when PM Netanyahu arrived for flight home

A terrorism scare gripped JFK Airport last night when intruders were spotted near airport grounds just as Israeli Prime Minister Benjamin Netanyahu arrived for his flight back home — but the trespassers turned out to be fishermen, law-enforcement sources said.

The alert was sounded at around 9 p.m., causing a massive air and water search of the airport perimeter by the NYPD, the Port Authority and other agencies.

At one point in the confusion, a message was broadcast that a Secret Service member was missing. The report proved to be false

By 10 p.m. it was determined that four fishermen had taken a boat into an area on the west side of JFK called Hamilton Beach, a restricted part of the airport’s property, sources said.

The quartet had gotten to within half a mile of Netanyahu’s plane, the sources said.

Had they been terrorists, they were in position to do real damage, the sources said.

“It’s another major breach of security,” said one law-enforcement source. “Luckily they were only fishermen and not terrorists.”

The men, whose identities were not released, were charged with trespassing.

In August, a stranded jet-skier got through the airport’s $100 million security net when his watercraft broke down.

He hopped a fence, walked across two runways and flagged down some workers in a building inside the airport.
