Rescuers continue to search for an estimated 20 girls who were at Camp Mystic in Hunt, Texas when deadly floods from the Guadalupe River swept through the camp.

Searchers are moving on foot through rough terrain, looking for survivors or victims’ remains in woods, culverts and other places.

Rescuers searched through the night early Sunday for 27 girls missing from a riverside summer camp in Texas, after torrential rains caused devastating floods that killed at least 50 people in the US state.
