Anders Behring Breivik, accused of killing of 77 people in a bomb and gun rampage in Norway last summer, was formally charged Wednesday with committing acts of terror and voluntary homicide, prosecutors said.
Prosecutors say he was psychotic at the time of the killings and should be transferred to "compulsory mental health care."
A fierce debate has raged over whether Breivik is mentally competent to face criminal punishment.
The mass killing was the single largest loss of life in Norway since World War II.
