(LONDON) -- "Around 10" people died in a shooting on Tuesday at an adult education facility in Orebro, Sweden, according to police.
The victims were found inside the school complex, police said during a press conference Tuesday night local time. The school is currently cordoned off.
The shooter was among the 10 dead, a Swedish police spokesperson told ABC News.
"The man we believe is the perpetrator is dead. He is among the 10 people who were killed," the spokesperson said.
Police don't yet know the motive of the shooting.
"We have no indication that it's terror, but we're not ruling out anything," the spokesperson, Lars Hedelin, said.
Swedish police didn't provide the identify of the shooter but said they're "no longer a threat to us."
The investigation is still ongoing, with police officers still searching the school to ensure there are no additional victims.
Police initially said five people were taken to the hospital. No ages of the victims have been given yet.
When asked how the number jumped from five to 10, Hedelin clarified: "We didn’t have a possibility to confirm until now that we had 10 people that were killed," adding: "I would say that all of them have been shot and all are adults."
Officials said in a statement they were urging the public to stay away from the Risbergska Skolan, a municipal education center in the Vasthaga area of Orebro. The school is for students over 20 years old, according to its website.
Law enforcement in the Bergslagen region began at about 1 p.m. local time to post a series of short statements, saying initially that a "major operation" was underway and the school was under threat of "deadly violence."
Police set up an information point for relatives to gather, and students were sent to nearby facilities.
Swedish Prime Minister Ulf Kristersson said this is a "very painful day for all of Sweden" and that "the government is in close contact with the Police Authority and is closely monitoring developments."
"My thoughts are also with all those whose normal school day was replaced with terror," Kristersson wrote on X. "Being confined to a classroom with fear for your own life is a nightmare that no one should have to experience."
The school is about 200 km, or about 125 miles, west of Stockholm, the capital.
