At least eight people were killed and many were injured in a crush when fans surged toward the stage during the opening night of the Astroworld music festival on Friday in Houston, officials said.

Houston Fire Chief Samuel Peña confirmed the casualty figures at an early morning news conference outside NRG Park.

Peña said that at around 9 p.m. the crowd that had gathered for a performance by popular rapper Travis Scott began to push toward the front of the stage, causing panic and injuries.
