More details from Friday night's deadly incident at a Houston music festival are emerging.

Rapper Travis Scott's Astroworld festival was marred by at least eight deaths and numerous injuries in what officials described as a crowd surge while the rapper was performing.

Officials declared a "mass casualty incident" just after 9 p.m. Friday during the festival attended by an estimated 50,000, Houston Fire Chief Samuel Peña told reporters at a news conference.

In the hours following the incident, a video began circulating on Twitter featuring Scott, 29, performing while police seemingly work to resuscitate a nearby attendee.
