Flash floods that swept through Texas over the Fourth of July weekend have left more than 100 people dead and more than a dozen others missing.

Over 100 people have died after heavy rain pounded Kerr County, Texas, early Friday, leading to "catastrophic" flooding, the sheriff said.

At least 56 adults and 30 children have been killed in Kerr County, Sheriff Larry Leitha said at a press conference, with more than two dozen victims yet to be identified. Local officials have faced angry questions about whether they could have warned people of dangerous flash floods in Texas Hill Country sooner.
