A gunman opened fire at an elementary school in South Texas on Tuesday, killing 19 students and two teachers.
The suspect was killed in the midday shooting at the Robb Elementary School in the town of Uvalde, Texas, about 80 miles (130 km) west of San Antonio.
The rampage is the latest in a string of high-profile mass shootings. The United States experienced 61 "active shooter" incidents last year, up sharply in the number of attacks, casualties and geographic distribution from 2021 and the highest tally in over 20 years, the FBI reported this week.
