Three people, including a teenage suspect, have died and several are injured after a shooting at a school in Wisconsin.
A teacher and a teenage student were killed in the attack at Abundant Life Christian School in the state capital Madison.
The suspect has been identified as a 17-year-old female student.
Police said the body of the teen was found by officers who stormed the school, suggesting the suspect killed themselves.
A handgun was recovered after the attack.
"Officers found multiple victims with gunshot wounds when they arrived at the scene," said Shon Barnes, chief of Madison Police.
"Officers located a juvenile, who they believed was responsible for this, deceased in the building."
Earlier, police said five people had died in the shooting, but later said that was incorrect.
At least six people were wounded, police said. Two students had life-threatening injuries and four other people had non life-threatening injuries.
"Today is a sad, sad day, not only for Madison, but for our entire country, where yet another police chief is doing a
press conference to speak about violence in our community," Mr Barnes said.
"Every child, every person in that building, is a victim, and will be a victim forever. These types of trauma don't just go away."
Video posted from the scene on social media showed a significant emergency response, including police, ambulance and fire vehicles.
The school is a private institution that teaches some 400 students from kindergarten through 12th grade, according to its website.
US President Joe Biden has been briefed on the shooting, the White House said.
Wisconsin governor Tony Evers said: "As a father, a grandfather, and as governor, it is unthinkable that a kid or an educator might wake up and go to school one morning and never come home.
"This should never happen, and I will never accept this as a foregone reality or stop working to change it."
There have been a total of 486 mass shootings in the US so far this year, according to the Gun Violence Archive.
Of the 15,992 killed in 2024, 236 were children between the age of 0-11 and 1,100 were teenagers between 12-17.
