An elementary school in Texas was the site of one of the deadliest mass shootings in recent United States history this week.
Nineteen children and two teachers were killed Tuesday in a shooting at Robb Elementary School in Uvalde, Texas, law enforcement officials said.
Seventeen people also suffered non-life-threatening injuries in the shooting, which unfolded midday Tuesday when an alleged 18-year-old gunman opened fire at the school west of San Antonio, authorities said.
The Uvalde school shooting joins the grim ranks of nearly a dozen other mass shootings that have taken place at music festivals, nightclubs and other schools in the past nearly quarter-century in America's unparalleled gun violence epidemic.
The incident makes it the second-deadliest shooting at an elementary, middle or high school in U.S. history -- behind the Sandy Hook Elementary School shooting in 2012 -- and the seventh-deadliest shooting in the country since the Columbine High School massacre in 1999.
These are the mass shootings with the highest death tolls in recent American history, based on an ABC News analysis.
