Texas floods: death toll rises as search and rescue turns into grim recovery operation

Residents observe day of prayer after 82 people killed and 10 girls and one camp counselor still unaccounted for

Residents in central Texas were observing a day of prayer on Sunday for at least 82 people killed and dozens missing in Friday's devastating flash flooding, as a search and rescue operation for survivors began to morph into a grim exercise of recovering bodies.

Relatives continued an anxious wait for news of 10 girls and one camp counselor still unaccounted for from a riverside summer camp that was overwhelmed by flash flooding from the Guadalupe River, which rose 26ft (8 meters) in 45 minutes on Friday morning after torrential pre-dawn rain north of San Antonio.
