Swedish police said on Wednesday that "erroneous narratives" were being spread on social media regarding the mass shooting on Tuesday at an adult education centre, the Nordic country's deadliest gun attack.

Those are the words of Swedish Prime Minister Ulf Kristersson, following what he described as the worst mass shooting in the country's history, with around 10 people killed. The shooting took place at an adult education centre - located on a campus with other schools - in the central city of Orebro at around 12:30 (11:30 GMT).

The shooting occurred at a center for adult education in the city of Orebro. The suspect is believed to be among the dead, officials said.
