8 people dead and several are injured at a music festival in HoustonHOUSTON — Fans attending a Houston music festival surged toward the stage during a performance by rapper Travis Scott, triggering panic in the crowd of tens of thousands. At least eight people were killed and many more hurt, authorities said.

The chaos unfolded Friday evening at Astroworld, a sold-out, two-day event at the NRG Park stadium. An estimated 50,000 people were in attendance.

"The crowd began to compress towards the front of the stage, and that caused some panic, and it started causing some injuries," Houston Fire Chief Samuel Peña told a news conference. "People began to fall out, become unconscious, and it created additional panic."Seventeen people were taken to hospitals, including 11 who were in cardiac arrest, Peña said, and "scores of individuals" were injured.

Event organizers had arranged for medical teams to be at the festival. But once the crowd surge began, those teams were "quickly overwhelmed," the fire chief said.

In a video posted to social media, Scott could be seen stopping the concert at one point and asking for aid for someone in the audience: "Security, somebody help real quick."

Houston Police Executive Assistant Chief Larry Satterwhite, who was near the front of the crowd, said the surge "happened all at once."

"Suddenly we had several people down on the ground, experiencing some type of cardiac arrest or some type of medical episode," Satterwhite said. "And so we immediately started doing CPR and moving people right then."

Satterwhite said he quickly met with promoters, who agreed to end the event "in the interest of public safety."
