Kylie Jenner has been criticized after she posted a clip of an ambulance tending to the injured at Houston's Astroworld Festival on Friday night.

Eight people were crushed to death and more than 300 were injured by a crush at Jenner's boyfriend's - rapper Travis Scott's - event.

Distressing video showed an unconscious male concertgoer being rushed to a medical assistance area after he passed out in an apparent stampede.

What Caused This To Happen?

The tragic incident happened after people surged towards the stage shortly after 9.15pm CST Friday night.

At least 23 people were rushed to a hospital - 17 of which during the worst of the incident, including a 10-year-old, police said.

The Houston Fire Department reported that 11 victims were in cardiac arrest and needed CPR. None of those killed or injured have been identified. Cops said 367 police officers and 241 security officers were working the event prior to the crush.

At one point fans were even recorded begging concert staff to halt the performance and help people escape the surge.

"People are f***ing dying, I want to save somebody's life," a man said as he climbed on a platform where a cameraman was filming the performance.

"That's somebody's kid! I want to save them!" he screamed but to no avail.

Astroworld Fest's organizers offered their condolences to the families of those killed in a statement Saturday.

Scott released his own statement where he shared his "devastation" at the loss of life.
