The last time Laor Abramov’s family heard from the 20-year-old former New Jersey resident, he was ducking bullets inside an Israeli bomb shelter — not more than an hour after radical Hamas militants attacked a party he attended.

“He phoned his dad in the morning — my brother — in the morning around 7:30, saying, ‘People are shooting at us,'” Abramov’s aunt, Yael Abramov told The Post on Tuesday.

“‘I am going into a missile shelter, a bomb shelter, and don’t worry,'” the aspiring DJ told his family. “‘I’m not going to be able to speak because it’s very noisy.’ After that, we didn’t know anything that was going on.

“There was no contact, couldn’t reach his phone,” Yael Abramov, a doctor who now lives in Canada, said in a telephone interview. “There was just horror stories of what’s going on there.

It wasn’t until hours later that a relative stumbled upon a photograph of Yaol inside the shelter — the lanky 6-foot-4 aspiring DJ stood out among more than a half-dozen revelers at a party that was disrupted by gunfire.

“I saw that photo and I was just filled with hope that he’s somewhere safe,” his aunt said. “Then I just found out [it’s] basically a death trap, those shelters.”

The following day the family was able to reach out to a survivor from the shelter, a now-hospitalized woman who remembered seeing Abramov there — and the horror that befell them.

“The shelter where we were hiding was threatened with terrorists,” the wounded woman told his father. “They had rounds and rounds that they threw inside and some of the young people there tried to throw them back out. Then they got in with their automatic runs and shot everyone.

“… Whoever was still on their feet standing, they grabbed them and put them on their pickup truck and drove away,” she said.

The woman “said Laor was there. Laor was being pulled away into the truck. That’s everything we know,” Yael Abramov said.

More than 1,000 Israelis — many of them women, children and the elderly — were killed when armed terrorists launched the surprise attack and stormed out of the Gaza Strip around 6:30 a.m. Saturday.

At least 150 Israeli civilians and soldiers who survived the onslaught were taken hostage. Laor Abramov’s family now prays that he survived after being hauled out of the bomb shelter shortly after the attack.

His mother is a US citizen who lives in New Jersey — where he lived until last year, when he returned to Israel to serve in the military, only to later decide to pursue his dream of being a DJ like his father, David Abramov, who had gained some fame behind the turntables himself.

Laor Abramov wasn’t working at the doomed rave party but was simply there to enjoy himself when the revelers were suddenly overwhelmed by armed terrorists who launched an unprovoked assault on them, his aunt said.

Rachel Meijer, Yael Abramov’s mother-in-law, said it’s just one of countless horror stories in her country.

“The feeling of safeness is gone totally,” she said. “Fifteen hundred bodies of Hamas were found in Israel, meaning there were thousands of warriors — and they came to slaughter. It’s Isis on steroids.

“And where is Biden?” she added. “Why aren’t the Americans taking care of their own citizens? This is the child of an American.”
