Flash floods in Texas have killed more than 100 people, many of them children. Heavy rains fell quickly in the predawn hours Friday in the Texas Hill Country.

Many of the victims were staying at Camp Mystic, an all-girls Christian summer camp located along the banks of the Guadalupe River. There were 10 campers and one counselor still unaccounted for at the time of the press conference Monday morning,

The downpours that swept away a children's summer camp and wreaked deadly havoc on huge areas of Texas caught holidaymakers by surprise. As the death toll passes 90 people, questions are being raised about whether adequate flood warnings were provided and why people weren't evacuated ahead of the deluge.
