8 dead after crowd surge at Travis Scott's Astroworld Festival in Houston

Eight people are confirmed dead and "scores of individuals" are injured after a crowd surge at the Astroworld music festival in Houston, officials said.

The "mass casualty incident" occurred after 9 p.m. Friday night when a crowd began to "compress" toward the front of the stage, "and that caused some panic, and it started causing some injuries," Houston Fire Chief Samuel Peña said early Saturday at a press conference. 

"People began to fall out, become unconscious, and it created additional panic," he said.
