Texas parents are frantically posting photos of their daughters and pleas for information as at least 23 campers from an all-girls summer camp remain missing after floods tore through the state’s south-central region.

The death toll from devastating floods in the Texas Hill Country rose to 24 Friday night, officials said, as the search for more than 20 people missing from a girls summer camp continued through the night.

Authorities have said thirteen people have died in Kerr County in the US state of Texas amid a bout of severe weather and flooding. Others remain unaccounted for - including around 20 children who had been at a summer camp.
