Pukkelpop videos: scenes from the deadly storm

(CBS/AP) - Vidoes have emerged from the freak storm that struck Belgium's Pukkelpop music festival. The storm shredded the annual outdoor festival Thursday evening, blowing down canvas tents, uprooting trees and flinging multistory metal scaffolding towers and racks of concert lights across the grounds.

Organizers said five people were killed and 140 injured, 10 of them seriously. As the videos below show, the deadly storm sent concert goers scrambling for cover as trees and buildings fell around them.

Officials said the dead were all Belgians, ranging in age from 15 to 59. They were not immediately identified. Officials canceled the last two days of the three-day Pukkelpop festival Friday and blamed unprecedented weather conditions in the town 50 miles (80 kilometers) east of Brussels.

Hilde Claes, the mayor of Hasselt, spoke of a "nightmare" and said the town had never seen a storm like the one Thursday.

The storm lasted barely 5 minutes. As the sky darkened, some of the 60,000-strong festival crowd ran for shelter from the rain and hail into the tents of caterers and festival sponsors. But Claes said three huge tents buckled under the force of the wind and the weight of the hail, sending hundreds back outdoors. As tent poles buckled, canvas roofs shredded, flapping in tatters in the wind.
