Two 14-year-old boys planned to kill pupils and teachers at their school in a re-enactment of the 1999 Columbine High School massacre, a court heard today.
The teenagers, both now 15, are accused of conspiracy to murder and other offences relating to an alleged planned attack at their school in the North Yorkshire market town of Northallerton.
The schoolboys, who sat in court with their mothers with one wearing his school uniform, have gone on trial at Leeds Crown Court today.
Paul Greaney QC, prosecuting, told a jury that the boys hero-worshipped Eric Harris and Dylan Klebold - the teenagers who killed 12 students and a teacher at Columbine High, in Colorado, before shooting themselves.
One of the boys downloaded a manual from the internet that provided instructions on the manufacture of nail bombs, grenades and napalm, it is alleged.iPhone transfer software
The Columbine killers were hero-worshipped by two Yorkshire schoolboys now on trial for allegedly planning a similar attack in their school

Internet searches such as 'how to shoot up the school' and 'what is the best weapon to shoot up a school with' were also discovered on the older boy's mobile phone, a jury was told.
Mr Greaney said: 'Eighteen years after the Columbine Massacre and nearly 4,500 miles away, two young teenagers in North Yorkshire became fascinated with Eric Harris and Dylan Klebold.
'Those two teenagers researched and discussed those killers and their interest in them turned to hero-worship. It was against that background that they plotted their own attack upon the school they attended.
'In that attack, they intended to shoot and kill other pupils and teachers against whom they held a grievance.
'They also, like their heroes, intended to deploy explosives and researched bombing-making techniques to that end.'
Mr Greaney said: 'They intended a re-enactment of the Columbine High School Massacre although fortunately, in the result, they were stopped before their plans were put into action.'
The defendants sat outside the dock, behind their lawyers, in Court 1 of Leeds Crown Court as Mr Greaney began to outline the case.
Both sat with their mothers and one was wearing school uniform.
Both deny a joint charge of conspiracy to murder relating to a period between December 31 2016 and October 29 2017
