MINNEAPOLIS (AP) — A shooting Wednesday at a Minneapolis Catholic school killed two children as they prayed and injured 17 other people, 14 of them kids, the police chief and mayor said. The shooter also died.

Gov. Tim Walz called the violence “horrific.”

The Minneapolis city government said the shooter had been “contained” after the gunfire at Annunciation Catholic School, and there was no longer any “active threat” to residents.

Walz said on social media that he had been briefed on the shooting.

“I’m praying for our kids and teachers whose first week of school was marred by this horrific act of violence,” Walz wrote on X.

Children’s Minnesota, a pediatric trauma hospital, said in a statement that five children were admitted for care. Hennepin Healthcare, which has Minnesota’s largest emergency department, said it was also caring for patients from the shooting.

As police, FBI and other federal agents and ambulances converged on the school, President Donald Trump said in a Truth Social post that he was briefed on the “tragic shooting” and that the White House would continue to monitor it.

The school was evacuated, and students’ families were later directed to a “reunification zone” at the school.

Dating to 1923, the pre-kindergarten through eighth-grade school had an all-school Mass scheduled at 8:15 a.m. Wednesday morning, according to its website. Monday was the first day of school. Recent social media posts from the school show children smiling at a back-to-school event, holding up summer art projects, playing together and enjoying ice pops.

At a meeting of Democratic officials elsewhere in Minneapolis, Democratic National Committee Chair Ken Martin noted the shooting and “unknown amount of victims.”

The gunfire was the latest in a series of fatal shootings in the city in less than 24 hours. One person was killed and six others were hurt in a shooting Tuesday afternoon outside a high school in Minneapolis. Hours later, two people died in two other shootings in the city.

Wednesday’s school shooting also followed a spate of hoax calls about purported shootings on at least a dozen U.S. college campuses. The bogus warnings, sometimes featuring gunshot sounds in the background, prompted universities to issue texts to “run, hide, fight” and frightened students around the nation as the school year begins.
