Four children have died after a man climbed the wall of a nursery and carried out a horrific attack in Brazil before turning himself in.

The 25-year-old arrived at the nursery in Blumenau, southern Brazil, on a motorbike before going on a rampage, attacking children who were in a park behind the school.

More to track.
