Camp Mystic, a 99-year-old Christian summer camp for girls in Texas Hill Country, was hosting 750 children this week when catastrophic flooding struck the Guadalupe River early Friday, leaving at least 20 children missing.

The death toll from flooding in central Texas rose to at least 24 people with 20 girls at a camp unaccounted for, officials said.

The Texas Hill Country, which was ravaged by severe storms Friday leading to at least 25 deaths and scores of both missing and rescued individuals, is expected to see inches of additional rain Saturday.
