At least 24 people have died after heavy rain pounded Kerr County, Texas, early Friday, leading to "catastrophic" flooding, the sheriff said.

Teams conducted dozens of rescues, and the emergency response continued as an unknown number of people remained unaccounted for.

Texas Hill Country was beset by death and disaster Friday as at least six people were killed and about 20 girls attending a summer camp were reported missing after months worth of heavy rain fell in a matter of hours,
