A Christian girls' summer camp in central Texas said on Monday that at least 27 campers and counselors were among those who perished in the catastrophic flooding over the July 4 weekend, while emergency responders still searching for dozens of missing people faced the prospect of more heavy rains and thunderstorms.

Meanwhile, anguished parents waited for word on the 10 young campers still missing from Camp Mystic, which was hit hard by floodwaters.

In Kerr County, home to Camp Mystic and other youth camps in the Texas Hill Country, searchers have found the bodies of 68 people, including 28 children, Sheriff Larry Leitha said.
