A deadly flash flood that swept through Texas, U.S., has killed at least 81 people, while about 41 are still missing.

Citing authorities, the New York Times on Monday reported that at least 68 of those killed in the floods, including 28 children, were in Kerr County, northwest of San Antonio.

It added that five people were killed in Travis County, three in Burnet County, two in Kendall County, two in Williamson County and one in Tom Green County.

While rescue operations are ongoing, the Kerr County Sheriff’s Office said that over 800 people have been evacuated from the area affected by the flood.

Torrential downpour on Friday unleashed a flash flood that tore through Texas, killing and destroying properties.

In a post on Truth Social on Sunday, President Donald Trump said, “I just signed a major Disaster Declaration for Kerr County, Texas, to ensure that our brave first responders immediately have the resources they need.

“These families are enduring an unimaginable tragedy, with many lives lost, and many still missing. The Trump administration continues to work closely with state and local leaders.”

He added, “Secretary of Homeland Security Kristi Noem was on the ground yesterday with Governor Greg Abbott, who is working hard to help the people of his great state. Our incredible U.S. Coast Guard, together with state first responders, have saved more than 850 lives. God bless the families, God bless Texas!”
