A local court has convicted a Finnish man and woman of plotting to kill dozens of people at a university and sentenced them to at least three years each in prison.

The Helsinki Regional Court found the pair, both aged 24, guilty of possessing weapons, ammunition and chemicals meant "for the mass murder of at least 50 people, chosen randomly."

The Friday verdict described how they met over the Internet in 2012, discussed mass murders and during the course of 15 months hatched a plan to slaughter people at the University of Helsinki. The court said their plan was prompted by feelings of hatred toward society, anger and revenge for being teased at school.

It was not clear if they would appeal.
