Several people have reportedly died after a shooting at an adult school campus in central Sweden on Tuesday afternoon.
The shooting at Risbergska School in Örebro, 125 miles west of Stockholm, left five people wounded, including the gunman, Swedish officials said. One was said to be in a serious condition.
Several people have since died of their injuries, local media reported, which has not yet been confirmed by the authorities.
Police did not immediately release other details, but told reporters that “the danger wasn’t over”.
At a news conference, local head of police, Roberto Eid Forest, said: “The investigation is somewhat unclear.
“It is unclear whether the shooting took place inside the school (building) or whether there may be more perpetrators.”
Police said that the gunman was one of the people hospitalised after the shooting.
Four of the five people who were shot underwent surgery, including one person who was seriously wounded.
Two others were described as stable and another was considered slightly injured, Jonas Claesson, regional director of health and medical services, said during the news conference.
Police said that no officers were shot.
The school, called Campus Risbergska, serves students who are over age 20.
The shooting erupted after many students had gone home following a national exam.
Teacher Lena Warenmark told local broadcaster SVT News that there were unusually few students on the campus on Tuesday afternoon after the exam.
She told the broadcaster that she heard around ten gunshots.
Students sheltered in nearby buildings, while other parts of the school were evacuated following the shooting, which began at around 12.30pm local time (11.30am GMT).
Andreas Sundling, 28, was among those forced to barricade themselves inside the school.
“We heard three bangs and loud screams,” he told 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.”
Prime Minister Ulf Kristersson said that it was “a very painful day for all of Sweden.”
“My thoughts are also with all those whose normal school day was exchanged for terror,” Mr Kristersson said.
“Being confined to a classroom with fear for your own life is a nightmare that no one should have to experience.”
