Two boys, aged 10 and 11, have been charged with attempted murder after a serious attack on two other children in Doncaster in South Yorkshire.
A 11-year-old boy suffered serious head injuries and is in hospital in a serious condition.
His nine-year-old friend was found bleeding from knife wounds and has undergone surgery.
As both suspects are under the age of 18, they cannot be named and neither can their victims.
The boys have also been charged with robbery after Saturday's attack.
It's important to remember that cases like this are very rare.
