A 12-year-old student suspected of fatally shooting a classmate and wounding two others in Finland told police that he was bullied at school, officials said, as a nation shocked by the attack held a day of mourning.

The suspect, who attended the school in the city of Vantaa, just outside Helsinki, was apprehended less than an hour following the shooting on Tuesday morning.
