A security guard tried to give a heads up to the band playing onstage right before the roof collapsed at the Dominican Republic nightclub that killed 221 people.

New video surfaced showing the moments before Tuesday’s early morning tragedy at Jet Set Club in Santo Domingo — and the guard dressed in a dark suit is seen on the side of the stage as merengue star Rubby Pérez performs in front of a packed crowd.

In the clip, the guard gestures at band members behind Pérez, then he shines a flashlight at them and says something. After that, the guard points the flashlight at the roof just before it collapses.

Other footage captures concertgoers frantically trying to escape the debris-filled club after the roof fell.

Perez, 15-year former MLB veteran Octavio Dotel and Monte Cristi governor and ex-MLB All-Star Nelson Cruz‘s sister Nelsy Cruz died in the collapse.

Dominican Republic President Luis Abinader visited the scene to offer hugs and support to those searching for friends and family. Rescue crews sifted through the rubble and found 189 survivors.

The helicopter that crashed into the Hudson River Thursday afternoon — killing all six passengers — was en route to its base to refuel, the tour company’s CEO revealed.

New York Helicopter Tour CEO Michael Roth told the Telegraph the pilot, whose identity remains unknown, confirmed they were heading back to base for gas, adding … “It should have taken him about three minutes to arrive, but 20 minutes later, he didn’t arrive.”

The chopper plummeted into the Hudson just off Jersey City, N.J. at 3:15 PM local time. Though a rescue mission commenced immediately, no survivors were pulled from the craft.

Spanish newspaper El Diario reported the family was celebrating the birthday of one of their children when the flight went down.

Heart-wrenching final photos of the family alive show them smiling in front of and inside the chopper before it took flight.

A cause of the crash has not been confirmed, but eyewitness accounts say the Bell 206 aircraft was seen falling apart before it hit the water. One video shows what appears to be a rotor blade freefalling separately from the aircraft.

Roth confirmed in a statement to the Post that “the main rotor blades weren’t on the helicopter” when it fell from the sky, adding that he is “devastated” by the accident.

Explaining the shock ofthe situation, he noted … “I haven’t seen anything like that in my 30 years being in business, in the helicopter business. The only thing I could guess – I got no clue – is that it either had a bird strike or the main rotor blades failed. I have no clue. I don’t know.”

Alessandra Ambrosio has always been that girl — smoking hot at every age — and at 44, she’s proving she’s not just keeping up, she’s still setting the bar on fire.

We all know the birthday girl slays the catwalk, but it’s like she has zero days off — her IG bikini pics are basically rivaling high-fashion campaigns.

Alessandra’s got years of practice under her belt, and she knows her angles — plus, she’s a pro at catching that sunlight just right to make that bronze glow pop.

The Brazilian bombshell’s all about getting cheeky too — flashing that bum, and of course, giving us the beach view to go with it.
