A masked man brandishing a sword broke into a school in Sweden on Thursday, killing a teacher and seriously wounding three other people, two of them children, before being shot by police.
The attack took place in the southwestern town of Trollhattan at a school for children aged between six and 15.
“One teacher has died at the scene,” local health officials said.
Two boys, aged 11 and 15, were in critical condition with stab wounds, while another teacher who was seriously wounded in the attack was also being operated on, hospital staff said.
The assailant, a man in his 20s who was shot by police at the scene, was also in critical condition they said.
Police were alerted about the incident at 10:10am (0810 GMT) and have already identified the attacker. They have not disclosed any information about him and the motive for the attack remains unclear.
Media reports said the assailant was wearing a Star Wars mask, and school children initially thought it was a prank or a Halloween costume.
