OSLO: Judge Wenche Elizabeth Arntzen announced on Tuesday the opening of the second trial day for Anders Behring Breivik, who is set to testify about the killing of 77 people in Norway in July.

Five and a half days have been allotted to the right-wing extremist's testimony, and many fear he will veer off to try to promote his Islamophobic ideology, which he claims justifies the "cruel but necessary" attacks.
