Chilling drone video captured the devastation wrought by a tornado that slammed into Nashville and other parts of Tennessee, killing at least 22 people in four counties, destroying buildings and leaving tens of thousands of residents without power.

“This does feel like a longer strip of the damage than the one 20 years ago, but I think you’re really going to need daylight to survey property damage,” Nashville Mayor John Cooper said, according to WKRN, which posted the video.

At least 30 people were injured in the state capital, where at least 48 buildings were flattened, with many more damaged, according to Fire Department Director Chief William Swann, Reuters reported.

Rescuers went door to door to search for anyone who may have been trapped or injured by the storm, which left an undetermined number of people missing, Gov. William Lee said.

The stark aerial footage showed large swaths of the city of 691,000 that resembled a war zone, with leveled houses, crumbled businesses, crushed vehicles and mounds of debris.

Public utility Nashville Electric said there were more than 44,000 customers without power early Tuesday.

Despite the widespread destruction, polling sites in Tennessee – one of 14 states holding primary elections on Super Tuesday – remained open unless otherwise noted, officials said.

“This was obviously a very strong tornado. There are multiple homes damaged, multiple people injured, multiple people still trapped,” Mt. Juliet police Capt. Tyler Chandler said in a video posted on Facebook.

“We need your help. And that means if you can stay at your house, please stay home,” he said in the suburb of Nashville.

“Sadly, 2 deceased adults have been located in the same, destroyed home in the tornado’s path (city limits). Currently, there is 1 adult still reported missing in the damage path. Crews continue to search rubble for anyone who could be trapped & not reported missing as well,” Mt. Juliet police said on Facebook.
