A bomb squad responded to a South Carolina beach on Sunday after Hurricane Matthew apparently unearthed old Civil War cannonballs from the sand.
Charleston County Sheriff's spokesman Maj. Eric Watson said in a news release that the cannon balls were found on Folly Beach Sunday afternoon, but bomb squad members couldn't get to it immediately because of the rising tide.
Once the ocean level goes down, Watson says technicians will make it safe. He warned residents might hear a small boom.

"Folly Beach ordnance detonation successfully completed. Small amount will be transported to Navy Base," the sheriff's office tweeted later.
The first shots of the Civil War were fired at nearby Fort Sumter in 1861.
