Flash floods in central Texas have killed 51 people, including 15 children, as rescues continue to search for people.
The worst-affected area, Kerr County, was responsible for the death of 43 people, with 27 children remaining missing from a Christian youth camp located along the River Guadalupe.
Multiple flash flood warnings remain in place over the weekend, with hundreds of rescues being deployed to affected regions.
The sheriff of Kerr County, Larry Leitha, said: "The work continues, and will continue until everyone is found."
About 850 people have been rescued in the first 36 hours from the floods, which have also ripped through Travis County and Tom Green County.
Texas Governor Greg Abbott said officials would ensure they locate "every single person who's been a victim of this event".
He added: "We will stop when the job is completed."
On Saturday, he confirmed that he had signed an expanded disaster declaration to boost search efforts.

Homeland Security Secretary Kristi Noem said President Trump is "devastated" by the loss of life from the floods.
Noem claimed "weather is difficult to predict" and the National Weather Service has done well over the years despite criticism over the lack of warning and preparations before the extreme weather event.
She added: "At times we have all wanted more time, more warning or more alerts," highlighting that Trump aims to fix the problem.
