An Australian politician is trolling the United States for its rate of mass shootings, the highest in the first world, after the latest deadly incident at a church in Texas.

“Dear US friends: here's Australian mass shootings 1979-2016 (via @SimonChapman6). See if you can figure out when we passed our gun reforms,” Andrew Leigh, an Australian parliamentary member, wrote in a tweet on Monday.

Leigh linked to a study published by the JAMA network last July that analyzes the drop in mass shootings after gun reform laws were past in Australia in which the government banned semiautomatic rifles and pump-action firearms while also starting a firearm buyback program.

The report found that after gun control passed in 1997, no fatal mass shootings occurred on Australian soil and there was also a “significant” downward trend for total firearm deaths. Before such laws were passed, Australia had faced 13 fatal mass shootings between 1979 and 1996.

Leigh’s tweet comes one day after Devin Kelley opened fire on a church service in Sutherland Springs, Texas, in what has become the state's deadliest mass shooting.

Kelley opened fire on a crowd attending Sunday mass, killing more than two dozen people while injuring about 20 others who were in attendance.

The fatal shooting has led to a renewed push among Democratic lawmakers for gun reform, who say enough is enough.

The church shooting comes one month after the deadliest mass shooting in modern American history took place in Las Vegas where a gunman sent a barrage bullets into a crowd attending country music festival, leaving nearly 60 dead and hundreds of others injured.

President Trump said Monday that a mass shooting was not “a guns situation,” but rather a result of the shooter’s “mental health.”
