The death toll from catastrophic floods in Texas reached at least 78 on Sunday, including 28 children, as the search for girls missing from a summer camp continued and fears of more flooding prompted evacuations of volunteer responders.

The death toll now stands at 70 in the wake of torrential rains and the resulting flooding in Texas. By far the greatest number of fatalities occurred in Kerr County, where 59 people are believed to be dead, according to officials, including 21 children.

Residents of Kerr County began clearing mud and salvaging what they could from their demolished properties as they recounted harrowing escapes from rapidly rising floodwaters late Friday.
