Three people are dead, including the shooter, after a student opened fire at a Christian school in Wisconsin.
The shooting took place 12 years and two days after one of the most notorious school shootings in US history: the massacre at Sandy Hook Elementary School in Newtown, Connecticut where 26 people were killed.
The incident in Wisconsin was the 323rd school shooting in the US this year.
So far, 2024 has seen the second-highest number of US school shootings since 1966, which is far back as the data goes.

Biden repeats calls for gun control
Outgoing President Joe Biden responded to the latest shooting by calling on Congress to enact gun-control legislation.
Similar calls have gone unheeded after almost every school shooting in recent memory.
"It is unacceptable that we are unable to protect our children from this scourge of gun violence," Mr Biden said in a statement.
"We cannot continue to accept it as normal."
President-elect Donald Trump has not responded to the Wisconsin shooting yet.
However in October Trump told the families of school shooting victims he was a strong advocate of the right to bear arms and that "good" people have guns it would keep the crime rate down.
