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.

At least 27 campers and counselors from Camp Mystic in Texas have died in devastating flash flooding that swept through the region, the camp announced. At least 109 people have died in the flooding that struck Texas Hill Country on Friday.
