A court in Serbia has convicted and sentenced to prison terms the parents of a teenage boy who shot dead nine pupils and a school guard last year and wounded six more people in primary school in central Belgrade.

A Belgrade court on Monday sentenced the parents of a 13-year-old boy to prison after he shot dead nine students and a security guard at an elementary school in Serbia's capital last year.

Shooter, Kosta Kecmanovic, was 13 when he committed the crime and therefore too young to face a trial, according to Serbian law
