An MTA supervisor allegedly accosted a Jewish woman on the streets of Manhattan for waving an Israeli flag, saying “f–k Israel” and flipping her the bird.

In a video shared on social media, Kenneth Foster, 57, can be heard telling the unidentified woman, “I got the right to say what the f–k I want, I’m American.”

Foster was walking down Columbus Avenue on the Upper West Side last Saturday with his mother when the woman’s flag “almost hit” him, he told The Post.

The video, which was posted by the Instagram pages Jew Hate Database and Jewish Lives Matter, claimed Foster was intimidating people putting up posters about Israeli hostages. But Foster claims he was unaware of any posters.

“I stated, ‘Why are you waving that flag that is part of an apartheid state?'” Foster said. “So she got mad, like they mostly always do when you talk about Israel.

“I said, ‘F you’ and ‘F Israel.’ I didn’t say nothing about Jews to her . . . now I have to defend myself,” Foster said.

He added he has nothing against Jewish people and should’ve “just walked away.”

“I’m against oppression of anybody — because I’m black, so I know what oppression is,” he told The Post.

The Bronx native said he has worked for the MTA for 36 years. Last year, he raked in over $143,000 for his role managing track maintenance and construction.

Following the Oct. 7 terrorist attack on Israel, Foster has been sharing continuous pro-Palestinian posts on his public Facebook page, where he also promotes a music production company.

“The MTA has no tolerance for hatred or discrimination,” said agency spokesman Tim Minton. “We have begun an investigation to determine all the facts.”
