HELSINKI (AP) — A court in Finland has convicted a man and a woman of plotting to kill dozens of people at the country’s largest university and sentenced them to at least three years each in prison.

In its Friday verdict, 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.” They also planned to rob a gun store to increase their arsenal for the attack, the court said.
