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.

At least 67 people are dead after heavy rain lashed Texas, leading to "catastrophic" flooding. Texas Gov. Greg Abbott said emergency responders remained in a search and rescue posture, hours after the flooding along the Guadalupe River inundated nearby areas.
