- The man who set himself alight is being treated in a hospital, Oslo police say
- Police do not know what motivated him to act in this way
- Breivik is on trial on charges of voluntary homicide and committing acts of terror
(CNN) -- A man set himself on fire Tuesday outside the court in Norway's capital, Oslo, where Anders Behring Breivik is on trial over terror attacks last summer that killed 77 people.
"We don't know much about his motives, but he set himself alight outside the courthouse. Police were quick to put the fire out and he has now been taken to hospital," Unni Groendal, head of press for Oslo police, told CNN.
The man is still alive, according to police. He did not try to force his way through the cordon as some reports have suggested, police said.
Norwegian daily VG reported that several court house employees ran out with water bottles to pour water over the man.
The area has been cordoned off, police told CNN.
The incident happened at about 1:45 p.m. local (7:45 a.m. ET), according to TV2 Norway.
Breivik is on trial on charges of voluntary homicide and committing acts of terror in the July 22 attacks. He admits carrying out an attack on a youth camp on Utoya Island and a bombing in Oslo that killed eight people.
He boasts of being an ultranationalist who killed his victims to fight multiculturalism in Norway.
Experts' assessment of Breivik's sanity will be a factor in determining what punishment he receives if convicted. Sentencing options could include imprisonment or confining him to a mental facility.
