Rudakubana will likely spend the rest of his life in jail for the murders of Bebe King, six, Elsie Dot Stancombe, seven, and Alice Dasilva Aguiar, nine, who were among 26 children attending the summer holiday event.

Rudakubana also pleaded guilty to 10 charges of attempted murder as well as to producing the deadly poison ricin and possessing an al-Qaeda training manual.

‘He would have killed each and every child’

The judge sentenced Rudakubana in his absence after he refused to return to court, having twice been removed for interrupting the hearing.

Rudakubana was deemed to be mentally fit to face prosecution.

‘Long-standing obsession with violence’

Heer said two of the girls suffered at least 85 and 122 sharp force injuries, which Rudakubana inflicted with a 20cm-long knife he had bought online from Amazon.

Shortly after the start of his sentencing hearing on Thursday, Rudakubana was removed from the dock after repeatedly shouting that he was unwell and wanted to see a paramedic.
