The top aide filling in for Mayor Eric Adams while he’s out of the country ripped the NYPD on Sunday for failing to keep hate-spewing anti-Israel protesters from the entrance of a Manhattan synagogue last week.

“[The demonstrators] were targeting New York Jews who were simply going to a synagogue to practice their religion,” acting Mayor Randy Mastro said on 77 WABC radio’s The “Cats Roundtable” show.

While protests are legal, the “hate”-screaming anti-Israel demonstrators should never have been allowed by the entrance to harass Jews going to synagogue, the deputy mayor said of Wednesday’s menacing rally outside the historic Park East Synagogue on the Upper East Side.

“Those protesters were too close to the entry of the synagogue. They said some very vile things,” Mastro said.

“They never should have been that close [to the entrance], never should have gotten to that stage.”

About 200 demonstrators had gathered outside the synagogue to heckle Jews attending an event by Nefesh B’nefesh, a Zionist organization that helps Jewish people immigrate from North America to Israel.

NYPD Commissioner Jessica Tisch already personally apologized to the synagogue’s congregants on Saturday over the department’s handling of the protest.

Mastro piled on by insisting to WABC radio host John Catsimatidis, “The police should have controlled that crowd more.

“It should’ve kept them farther away from the entrance,” said the city official, who has been serving as acting mayor while Adams traveled overseas to Israel and Uzbekistan.

“They were literally at the door of the synagogue, shouting … things like, ‘Globalize the Intifada’ and urging resistance to ‘take another settler out’ and saying vile things like ‘We don’t want no two-state solutions. We want the whole thing,’ ” Mastro said of the demonstrators.

“That just is not acceptable in our city,” he said.

“We have to protect our houses of worship and in particular the targets of these protests — our synagogues — so that New Yorkers, who are religious and practice their religion in peace, not be threatened, not be harassed, not be terrorized.

“That’s what Jews are experiencing in our city,” Mastro said. “I never thought I’d see it in my life.”

The city is going to have to “find the right balance” by allowing Jews and others the right to worship without being harassed while preserving the right to free speech and protest, he said.

Adams was set to return to the Big Apple sometime Sunday.

Supervisors with the Manhattan North Precinct handled the permit and security for the protest.

Tisch told a crowd of 150 congregants attending service at Park East Synagogue on Saturday that the NYPD failed to keep the front entrance clear and ensure “people could easily enter and leave shul.”

“That is where we fell short, and for that, I apologize to this congregation,” the commissioner said during a 10-minute speech, which drew a standing ovation.

“Our plan didn’t include a frozen zone at the entrance. As a result, the space right outside your steps was chaotic.”
