Dozens of people are dead in central Texas in what officials called a "mass casualty event" after devastating flash floods slammed Hill Country, with water rescues taking place along the Guadalupe River.

A t least six people were killed and more than 20 children were missing from a girl’s summer camp after torrential rain caused widespread flooding in parts of central Texas. Several victims, both children and adults, were recovered in cars and in water, authorities said. The number of deaths is expected to rise.

Texas Hill Country was beset by death and disaster Friday after multiple fatalities were reported from months worth of heavy rain that fell in a matter of hours.
