In the U.S. so far this year, more than 100 children aged 6 and under have unintentionally shot somebody.
On Sunday, a Minnesota boy became the latest added to the list.
The shooting happened in Deer Creek, Otter Tail County, with the local sheriff's office confirming a 3-year-old boy was shot by a 5-year-old boy.
Fortunately the boy is in a stable condition at Children's Hospital in Minneapolis, according to the Alexandria Echo Press.
Police told the newspaper it was reported as an accident, but the shooting is under investigation.
In Minnesota, it's a gross misdemeanor to store or leave a loaded gun where a child under the age of 18 is likely to gain access to it.
An everyday occurrence in America
Both boys involved are now added to the shockingly long list of children who shoot or have been shot by other children in America.
The Child Firearm Safety Alliance keeps records of this based on media and police reports. Its database shows there have been 105 incidents in the U.S. so far in 2017 where a child under the age of 6 has unintentionally shot someone.
In reality there are likely to be more than this, with the CFSA's numbers not definitive.
The CFSA list of child-involved shootings (covering all ages of children) only includes three from Minnesota in 2017, but this list from gun safety advocates Everytown shows 5 this year.
This includes an incident recently in St. Cloud, when a 3-year-old boy shot himself with his father's allegedly improperly stored gun. He was taken to the hospital with non-critical injuries. Police say his father is a convicted felon who himself was not allowed to possess a firearm.
In most cases involving children discharging firearms unintentionally, they shoot themselves. Other than this, they're most likely to shoot siblings or other family members.
On a wider scale, just under 1,300 children die every year from a gun-related injury, of which 53 percent were homicides, 38 percent suicides, 6 percent unintentional and 3 percent either by police or "undetermined," CNN reports.
