A masked and black-clad man entered a Swedish school cafeteria Thursday with a sword and began slashing victims, killing one and injuring at least four others, including one adult.
Police shot the murderer, reportedly to be in his 20s. His condition is not known but initial reports that he was killed have been retracted.
Two of the wounded students, ages 13 and 15, suffered serious injuries.
Many students thought the appearance of the man with a sword was some kind of stunt, and one of them told a Swedish broadcast station:
He wore a mask and black clothes. There were students asking to take pictures with him and touch the sword.
The identity of the attacker has not been revealed.
No evidence has yet been provided that he was a Muslim, and the idea was not even suggested, even though the terrorist wore black clothes and was armed with a sword, two characteristics of the Islamic State (ISIS).
