Commissioners in Kerr County, Texas, are set to meet Monday in their first official court hearing since more than 100 people, including children and counselors at a summer camp, were killed in catastrophic flooding last week.

Thirteen people are dead and more than 20 people unaccounted for after heavy rain lashed Texas, leading to "catastrophic" flooding. Children are among the dead, and about 23 campers from a summer camp in the area, Camp Mystic, are unaccounted for, said Lt. Gov. Dan Patrick, who has taken on the duties of acting governor.
