Children wounded in school shooting in Finland
A suspect, who is also understood to be a minor, has been arrested.
The school has 800 students and 90 staff. Witnesses told public broadcaster YLE that two ambulances had left the scene.
Police said all those caught up in the incident were minors and three of them had been wounded.
Viertola school has students aged seven to 15 of both primary and middle-school age. Like other Finnish schools, children had just returned to classes after the long Easter weekend.
