Be careful who you talk to when you’re on vacation.

Chilling new footage shows the moment an Iranian-born college student calmly admits to stabbing a man she met on a dating app as revenge for the US killing of a top military commander from her home country in 2020.

Police body camera footage shows Nika Nikoubin, 22, confessing that she stabbed her Plenty of Fish date in the neck as they had sex in a Las Vegas-area hotel room in March because she wanted to “spill American blood.”

“We were drinking a little bit and then — I guess we started to get into it and then I stabbed him,” Nikoubin says in the footage, obtained by FOX 8.

Asked by the officer why she attacked her date, Nikoubin, then a student at UCLA, said it was to avenge the death of Islamic Revolutionary Guard Corps commander Qassem Soleimani.

“I guess [it was] out of spite and revenge. I mean the US killed Soleimani. Lots of blood spilled,” she said. “So, I feel like it’s fair that American blood be spilled.”

She added, “I just felt like somebody on American soil should die because he also died.”

Nikoubin — who allegedly suffers from paranoid personality disorder — is shown in the footage wrapped in a towel, apparently inside the Sunset Station Hotel and Casino in Henderson, where she was later arrested.

As she casually recounts the events of the night, Nikoubin says her date was blindfolded during sex when she stabbed him with a pink knife to “hurt” but not kill him.

“’Did you plan on meeting [the victim] to hurt him?” the cop asks in the video.

“Yes,” she replies.

“To kill him or just to hurt him?” the officer asks.

“Hurt him,” she said.

Before the bizarre confession, police had found Nikoubin naked in a utility area on the 14th floor of the hotel, FOX 8 reported.

Nikoubin was later charged with attempted murder and two counts of battery. She posted $60,000 bail and was later placed on house arrest.

Her date, who has not been named, survived but suffered at least two cuts on his neck.

Soleimani, who headed the expeditionary Quds Force of the IRGC, was killed in a drone strike in January 2020 shortly after arriving at Baghdad’s airport.

Earlier this year, an IRGC member was indicted by the Justice Department and accused of offering $300,000 to assassinate President Donald Trump’s former national security adviser John Bolton, long an advocate of regime change in Iran.
