The mass shooting in El Paso, Texas, on Saturday, that left at least 20 dead and 26 injured appears to be the deadliest shooting in the United States this year.
It also falls into the top 10 deadliest mass shootings in modern American history.
The grim tally comes less than a week after another gunman, a 19-year-old, opened fire with what has been described as an assault-style rifle at the Gilroy Garlic Festival in California, killing two children and a man before being shot by police and ultimately killing himself.
These are the deadliest mass shootings on U.S. soil, and other mass shootings:

Early 1900s and prior:Dozens of earlier non-war massacres in the United States have left hundreds dead. Often racially motivated, these shootings date back to before American independence. A selection of these shootings are believed to have killed numbers between five and 300 people.
In May 1921, approximately 300 black Americans were killed during the Tulsa Race Massacre, which destroyed Oklahoma's "Black Wall Street," according to the Smithsonian.
In November 1887, white vigilantes shot and killed between 30 to 60 unarmed black sugar plantation field hands, who were on strike, according to NOLA.com.
During the post-civil war Reconstruction era, thousands of black Americans were killed in what is considered one of the most violent times in U.S. history. In April 1873, as many as 150 black Americans were killed when a white mob clashed with a black militia during the Colfax massacre.
