A teenage student opened fire Monday at a school in the northern US state of Wisconsin, killing two and injuring several others before being found dead, officials said.
Shon Barnes, police chief in the state capital Madison, told a news conference that a teacher and a teenage student died at the Abundant Life Christian School, a private Christian school for children aged five to 18.
He declined to share the gender or exact age of the suspect, who attended the school of around 400 pupils, saying "as difficult as today is, that's still someone's child that's gone."
Two students were being treated for life-threatening injuries, while four others were in hospital in a non-critical condition.
A handgun was recovered at the scene, Barnes said, adding that the suspect's family was cooperating with the police investigation.
Monday's violence is the latest in a long line of school shootings in the United States, where guns outnumber people and attempts to restrict access to firearms face perennial political deadlock.
Underlining the commonplace nature of mass shootings, the police chief said some medical personnel responding to Abundant Life came directly from training for such an event.
"I think we can all agree that enough is enough," Barnes told reporters.
"We have to come together to do everything we can to support our students, to prevent press conferences like these from happening again and again and again."
US President Joe Biden condemned the shooting as "shocking and unconscionable" and said the tragedy underscored yet again the need for tighter gun laws.
"It is unacceptable that we are unable to protect our children from this scourge of gun violence. We cannot continue to accept it as normal," he said in a statement.
"We need Congress to act. Now."

Police were alerted to the shooting by someone at the school shortly before 11:00 am (1700 GMT).
"When officers arrived, they found multiple victims suffering from gunshot wounds" and also "located a juvenile who they believe was responsible for this, deceased in the building," Barnes said.
"We believe the shooter was a student at the school," he added, saying police officers "never fired their weapons."
Wisconsin Governor Tony Evers said in a statement that "we are praying for the kids, educators, and entire Abundant Life school community as we await more information."
This year, there have been at least 487 mass shootings -- defined as a shooting involving at least four victims, dead or wounded -- across the United States, according to the Gun Violence Archive.
At least 16,005 people have been killed in firearms violence in the United States this year, not including suicides, GVA reported Monday.
In September a 14-year-old boy killed four people, including two students, at a high school in the state of Georgia, before being taken into custody.
Nineteen students and two teachers were shot dead in May 2022 when an 18-year-old gunman stormed their Uvalde, Texas elementary school and opened fire.
