A pro-Palestine activist tore down Greek banners from a restaurant after mistaking them for Israeli flags.

The woman posted a video online of her ripping down the flags outside a gyro in Montclair, New Jersey while yelling: “Free Palestine, b----.”

An employee of the restaurant watched her in astonishment from the counter, prompting the woman to shout: “What you looking at?”

“You know damn well there’s a genocide. You know there’s a genocide. I’m taking this s--- down.”

She appeared to be tearing down the flags from the restaurant while holding her phone in her free hand.

At one point, the video shows her moving a chair up to a wall and putting it down with a clang, apparently to reach flags located above the front of the building.

According to the New York Post, the incident took place at Efi’s Gyro, which bills itself as “the friendliest restaurant in town”.

“I don’t stand for this. There’s genocide. And I don’t stand for Zionism,” the woman, who goes by “Ambamelia” on TikTok, continued.

“They’re killing children,” she added, as two employees of the restaurant stepped outside to confront her.

A man who apparently worked for the restaurant then repeatedly explained the flags were Greek.

“Oh I thought it was Israel, my bad,” the woman excused herself.

Efi Mihalis, the owner of Efi’s Gyro, confirmed that the attack was real but had taken place in March, and accused the woman of destroying her property.

“It was not a skit as some people believe,” she told The New York Post. “This was not planned nor was it calculated in any way,”.

Ms Mihalis added that everyone had been “taken aback” when the flags were torn down.
