Five people have been shot at an education centre in central Sweden, police say.
The shooting happened in Orebro, 200km (124 miles) west of the capital, Stockholm, on Tuesday afternoon.
Police said “the danger is not over” and warned the public to stay away. The extent of the injuries is unclear – but police say no officers have been shot.
“This is currently seen as an attempted murder, arson and aggravated weapons offence,” they said in a statement.
A press conference from officials is expected at 15:30 local time (14:30 GMT).
The shooting – which occurred just before 13:00 – apparently targeted a Komvux, or adult education centre, which 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.
Police say students at nearby schools are being kept indoors “for security purposes”.
Nearby hospitals are clearing their emergency rooms and intensive care units to free up space for patients, local reports said.
Teacher Lena Warenmark told SVT, Swedish public radio, she heard around 10 gunshots close to her study.
“The news of an attack at Orebro is very serious,” justice minister Gunnar Strommer told SVT.
