The attack on Tuesday - described by Sweden's prime minister as the "worst mass shooting" in the country's history - happened at a school for adults.

Around 10 people were killed in a school shooting in Örebro. The damage at the crime scene was so extensive that investigators were unable to be more definitive, said Roberto Eid Forest, head of the local police.

Police have said "around 10 people" have died in a shooting at a Swedish education centre. The shooting took place in the city of Örebro, around 200km (125 miles) west of the capital Stockholm, with reports claiming the gunman opened fire with an automatic weapon.

Police said they do not know the motive but do not believe it is terrorism, adding they "had no warning sign" about the attack. Officers are working to identify the perpetrator and the victims.

The king and queen visited the scene of the tragic event that occurred on Tuesday and Swedish flags were flown at half-mast to honor the victims.
