Sweden shooting: Recap response - as it happened
Police said at least 11 people had been killed in the shooting.
The gunman is believed to be among the dead, officers said.
Here is everything we know about the shooting so far.
What happened?
Police were alerted to shots being fired at Campus Risbergska adult education centre just after 12.30pm local time (11.30am UK time) on Tuesday.
The violence broke out after many students had gone home following a national exam. Video footage from the scene showed a large police presence and other emergency vehicles.
Police later said at least 11 people had been killed, and that the suspect appeared to have acted alone.
Officers added on Wednesday that the gunman's motive is still not known.
Three women and two men, all with gunshot wounds, were taken to hospital and underwent surgery, officials said.
All were in serious but stable condition after being admitted with life-threatening injuries. Another woman was treated for minor injuries and was stable.
Two of the victims were in intensive care, regional director of health and medical services Jonas Claesson said.
All the victims were over the age of 18, officials said.
Students that were sheltering in nearby buildings, and other parts of the school, were evacuated following the shooting.
Campus Risbergska serves students who are over the age of 20, according to its website.
Primary and upper secondary school courses are offered, as well as Swedish classes for immigrants, vocational training and programmes for people with intellectual disabilities.
What we know about the suspect
The suspect remains unnamed, but police confirmed they are a male.
In their evening update on Tuesday, police said they believed the suspect had also died.
Speaking on Wednesday, police said the perpetrator appears to have shot himself.
They said he was not known to officers beforehand, and a motive still remains unclear.
'Three bangs and loud screams'
Teacher Lena Warenmark told SVT News that there were unusually few students on the campus on Tuesday afternoon after the exam. She also told the broadcaster that she heard probably 10 gunshots.
Andreas Sundling, 28, was among those forced to barricade themselves inside the school.
"We heard three bangs and loud screams," he told the Expressen newspaper while sheltering in a classroom.
"Now we're sitting here waiting to be evacuated from the school. The information we have received is that we should sit and wait."
Pavel Koubak, a photographer who was in the area at the time of the attack, said that he saw at least three police helicopters in the sky.
"I was talking to a guy riding a bicycle who passed through the area," he told Sky News presenter Kamali Melbourne.
"He had a friend that was working inside the school that had sent him a text message that there was automatic rifle fire. He was laying down on the floor inside the school."
Asked whether gun violence was rare in the area, Mr Koubak said it was not.
"We've had plenty of shootings around Sweden and also in Orebro in the last couple of years. But, this seems to be sort of a bigger magnitude," he said.
"I think [the police] are pretty educated on these types of situations nowadays. There was a pretty quick response from the big unit of police and lots of helicopters very, very quickly after the alarm."
What have the police said?
Police said they carried out investigations at various addresses in Orebro, with technical personnel working at the scene.
"At present, the police believe that the perpetrator acted alone, but we cannot rule out more perpetrators connected to the incident," the update on the Swedish police's website said.
Police added that they "had no warning sign" about the attack.
Officers are also working to identify the perpetrator and the victims.
What has the government said?
Sweden's prime minister Ulf Kristersson said on Tuesday that the tragedy is the worst mass shooting in the country's history.
"Today, we have witnessed brutal, deadly violence against completely innocent people," Mr Kristersson told reporters.
"This is the worst mass shooting in Swedish history. Many questions remain unanswered, and I cannot provide those answers either.
"But the time will come when we will know what happened, how it could occur, and what motives may have been behind it. Let us not speculate," he said.
Meanwhile, the country's king Carl XVI Gustaf said the shooting was a "terrible atrocity".
"We send our condolences tonight to the families and friends of the deceased. Our thoughts at this time also go to the injured and their relatives, as well as to others affected.
"My family and I would like to express our great appreciation for the police, rescue and medical personnel who worked intensively to save and protect human lives on this dark day."
