At least three people have been injured in a stampede at Travis Scott's Astroworld Festival, reports People.

According to ABC13 the injured festival-goers were transported to a hospital with minor leg injuries after being trampled as they tried to enter the festival before it began at NRG Park in Houston yesterday.

Scott posted video from outside the festival when barricades collapsed prompting hundreds of fans to storm the venue. His Instagram post included the message "be safe rage hard."

According to ABC13, gates didn't open until noon, however fans began queuing as early as Friday evening to secure prime positions.

The festival is predicted to have drawn crowds of around 50,000 people. Take a birds-eye look below.
