Sweden has reacted with shock to the killing of a teacher and pupil at a school in the west of the country, near Gothenburg, by a sword-wielding man.
Police say the attacker, who was shot dead by police, is being investigated for possible far-right sympathies.
The attacker, 21, was seen posing for a photograph with students, who thought he was dressed for Halloween, before going on the rampage from classroom to classroom, sending panicked students fleeing from the school building.
