A major search and rescue operation is continuing through the night in Texas after flash floods killed at least 24 people and left many girls missing from a Christian summer camp.

Teams conducted dozens of rescues, and the emergency response continued as an unknown number of people remained unaccounted for.

Texas parents are frantically posting photos of their daughters and pleas for information as more than 20 campers from an all-girls summer camp remain missing after floods tore through the state’s south-central region.
