Some 27 people, including nine children, have been confirmed dead after flash floods in central Texas, authorities said on Saturday, as rescuers continued a frantic search for survivors including dozens still missing from a girls' summer camp.

At least 10 inches of rain poured down overnight in central Kerr County, causing flash flooding of the Guadalupe River.

Parents are seeking answers as between 23 and 25 girls from Camp Mystic in Hunt, Texas, remain missing after a devastating flood. Those seeking information on loved ones are urged to call the Red Cross.
