The death toll from catastrophic floods in Texas reached at least 78 on Sunday, including at least 28 children, as the search for girls missing from a summer camp entered a third day and fears of more flash flooding as rain fell on saturated ground prompted fresh evacuations.

Families sifted through waterlogged debris Sunday and stepped inside empty cabins at Camp Mystic, an all-girls summer camp ripped apart by flash floods that washed homes off their foundations and killed at least 78 people in central Texas.
