Travis Scott says he is 'absolutely devastated' by death of eight people at rap concert

Authorities in Texas were investigating Saturday a tragedy in which the crowd at a huge Travis Scott rap concert surged toward the stage in a crush that killed eight people and wounded at least 17 more.

Around 50,000 people were in the audience at Houston´s NRG Park Friday night when the crowd started pushing toward the stage as Scott was performing, triggering chaotic scenes.

"People were being pushed, people were being trampled, and then as I fought my way out of there, I saw people on the ground," Logan Morris, a Dallas native who was at the show, told AFP.

Raul Marquez, 24, said he saw a lot of drinking and drug use in the crowd.

"And they got hot and just dancing and it all caved in and just, they couldn´t breathe, and passed out left and right," he said.

"Some people didn´t care and just stomped on them or ignored them. It was intense," Marquez said.

Houston Mayor Sylvester Turner said the crush left at least eight people dead and 17 to 23 injured.

Turner told CNN that authorities are looking at video footage, talking to witnesses, concert organizers and people who were hospitalized.

"So we´re looking at everything," Turner said.

Houston is known for staging high profile events, he said, but "we´ve never had anything like this occur."

More than 300 people were treated on the scene for minor injuries in the first night of the two-day Astroworld Festival, which Scott helped organize, authorities said.

Scott halted his act several times when he saw fans in distress near the stage.

Survivors described chaotic scenes of people squeezed up against one another with many struggling to breathe.

Gavyn Flores, 18, said he was standing on the edge of the crowd near a barricade and could not move, for hours on end. He said he tried to hoist people over that wall.

"People were trying to get out, but you can´t move. So there kind of wasn´t a point of trying to get out, because they couldn´t. But if they could, we were trying to help them get thrown over," Flores told AFP.

"I am absolutely devastated by what took place last night," Scott tweeted Saturday. "My prayers go out to the families and all those impacted by what happened at Astroworld Festival."

More than 360 police officers and 240 security guards were on hand for the festival.

Senior Harris County official Lina Hidalgo said it was "an extremely tragic night."

"Our hearts are broken, people go to these events to have a good time, to make memories," she added.
