At least eight people are dead after a crowd surged toward the stage at a massive Houston concert, causing panic and chaos, authorities said.

Over 50,000 people were at the first night of this weekend's sold-out Astroworld music festival at NRG Stadium when, around 9:30 p.m. local time, "the crowd began to compress toward the front of the stage," Houston Fire Chief Sam Pena told reporters Friday night.

"That caused some panic, and it started causing some injuries," Pena said.

Pena described the chaotic scene in an interview with ABC News' Gio Benitez on "Good Morning America" Saturday.
