Six pupils have been excluded from school for making death threats to a classmate on Facebook after he admitted supporting British troops.
Five Muslim boys and one white girl, all aged 12, have been disciplined following the incident.
The yobs threatened to attack terrified Darius Gill, 13, with knuckle dusters and knives in revenge for not supporting Islamic extremists.
The chilling threats came hours after Darius - whose father is Asian - posted a touching tribute to the thousands of squaddies who have lost their lives defending Britain.
One message - littered with spelling mistakes - said: 'Fight on Monday gonna be heavy knuckle dusters nd knifes hopefully I don't die.'
His friend added: 'ill bang him ma slef am a terrorist.'
One of the thugs also posted a chilling picture of himself holding a rifle.
Shockingly, other pupils - who have set up a Muslim Defence League which celebrates British deaths in Afghanistan - also added comments condemning Darius.
Fortunately Darius' mother Clare Allington read the comments on Monday morning - the day of the promised attack - and immediately pulled her son out of school.
Yesterday Clare, 42, from Coventry, said: 'I logged on and it broke my heart. I was reading all sorts about knuckle dusters, knives and death.
'They were planning to attack him at school that day so I rang the school straight away.
'I usually keep an eye on what Darius posts on Facebook.
'I have his password and usually check it every day but didn't last weekend until I was at the Warwick University campus on Monday.
'If I hadn't read the threats and pulled my son out of school he could be dead.
'They might just be school children but they are fanatical and dangerous.
The threats have to be taken seriously.
The children were excluded from the Sidney Stringer Academy in Coventry following the Facebook bullying campaign
'My son wrote supporting the British troops in Afghanistan and also said he was sad so many soldiers had died.
'The so-called Muslim Defence League which has been set up in the school by a number of pupils believe that Darius should join them in hating British soldiers.
'It's appalling and extremely upsetting for Darius.'
Shockingly, one of the thugs bragged about being quizzed by police and still threatened to attack Darius.
He posted: 'IM IN TROUBLE WIV DE POLICE CUZ OF SUSSPICIAN OF THREAT TO DARIUS OVER FB U HAVE A RITE TO REMAIN SILENCE!!! (JOKES) BUT IM IN TROUBLLE WIV DE POLICE IM BANGGIN DARIUS THURSDAY NO1 JUMP IN 1 v 1.'
Principal Wendy Thomas said Facebook was an increasing concern for schools.
She said: 'Darius is the victim of bullying. All the students involved have told me they did not mean what they said but they will learn a hard lesson from this.
'Facebook is a big concern for schools and we urge all parents to monitor what their children say on the site.
'As soon as the school was notified about the comments on Monday, we interviewed the pupils.
'No weapons were found on any of the pupils. We notified the police and they are investigating the incident.'
The students attend the 1,250-pupil Sidney Stringer Academy in Coventry.
Muslim pupils make up 65 per cent of the pupils which caters for children aged 11 to 18.
