Devastating floods across central Texas have killed at least 51 people after a storm pounded the region. Texas Gov. Greg Abbott issued a proclamation declaring Sunday as a day of prayer across the state in response to the flooding.

Anguished parents waited for word on the more than two dozen children still missing from Camp Mystic, a Christian girls' camp.

Flash-flood warnings and watches remained in effect for parts of Central Texas, dimming hopes that more survivors would be found.
