Police say about 10 people have been killed in a shooting at an education centre in central Sweden, including the suspected gunman.
The shooting at Risbergska school in Orebro, 200km (124 miles) west of the capital, Stockholm, took place on Tuesday afternoon.
Police said the perpetrator was not previously known to them and there was no immediately identifiable motive. He was believed to be acting alone, they said.
They warned on Tuesday evening the death toll could continue to rise as several people had been injured.
“This is an extremely tragic incident,” said Orebro police chief Roberto Eid Forest.
Earlier, the Swedish Prime Minister said it was “a very painful day for all in Sweden”.
A number of the injured have been taken to hospital, with at least four people undergoing operations.
Police had initially said the attack was being investigated as an attempted murder and arson attack.
In the evening briefing they confirmed there didn’t appear to be a “terror” motive behind the attack.
Police heard reports of a shooting taking place at Risbergska school – an adult education centre – at 12:33 local time (11:44 GMT). The facility sits on a campus that is home to other schools.
These centres are attended primarily by people who have not finished primary or secondary school.
Earlier, students at several nearby schools were being kept indoors “for security purposes”.
“We don’t want members of the public to go there,” Forest warned.
Nearby hospitals had cleared their emergency rooms and intensive care units to free up space for patients, local media reported.
Orebro University Hospital wrote in an update that five people injured by gunshot wounds were treated at its emergency room. An additional sixth person, not injured by a guns, had “minor injuries” treated, it said.
Teacher Lena Warenmark told SVT, Swedish public radio, she heard around 10 gunshots close to her study.
The Prime Minister Ulf Kristersson said that today is “a very painful day for all in Sweden” as he shared that those who had a “normal school day” replaced “with terror” are all in his thoughts.
“Being confined to a classroom with fear for your own life is a nightmare that no one should have to experience,” Kristersson said in a post on X.
“The government is in close contact with the Police Authority and is closely monitoring developments.”
His justice minister, Gunnar Strommer, echoed those remarks, telling local broadcaster SVT “the news of an attack at Orebro is very serious”.
