Officials in Texas say at least eight people are dead and several others have been injured in a crowd surge at the Astroworld Festival on Nov. 5. 

Houston Fire Chief Samuel Pena told reporters the compression of the crowd toward the stage occurred while Travis Scott was performing.

Crews overwhelmed by thousands of rescue calls during one of the heaviest downpours in U.S. history have had little time to search for other potential victims, but officials acknowledge the grim reality that fatalities linked to Harvey could soar once the devastating floodwaters recede from one of America’s most sprawling metropolitan centers.

A second person was killed on Aug. 26 as Hurricane Harvey, the most powerful storm to hit Texas in more than 50 years, roared inland, knocking out power to more than 200,000 people and threatening catastrophic flooding.

The second fatality was an elderly woman who was killed as she drove through flooded streets on Houston's west side on Aug. 26 night, a Houston police officer said.
