An estimated 600 Muslim children have been withdrawn from a school in protest against lessons about homosexuality and gender.
The pupils, aged between 4 and 11, are being kept home from Parkfield Community School in Birmingham to protest the school's 'No Outsiders' programme, which teaches children about LGBT lifestyles.
The mass exodus represents about 80 per cent of the school's entire enrolment.
The Alum Community Rock Forum told Birmingham Live that the pupils were pulled out of the classroom, because the school was 'undermining parental rights and aggressively promoting homosexuality'.

The exodus represents about 80 per cent of the school's entire enrolment, which is 98 per cent Muslim
'Dialogue, petitioning and protests by parents have been repeated and arrogantly ignored,' the forum said.
'Our children, our choice - work with parents not against them.'
Friday's action comes after weekly demonstrations against the school's programme, including one that was attended by 300 parents and children last month.

Some Muslim demonstrators said at the time they would rather leave the UK than allow their children to continue attending Parkfield Community School.
Some joined in with the chants and held placards reading: 'Education not indoctrination.'
One child carried a handwritten sign which said: 'Let kids be kids.'
Parents kept their children out of lessons for the first hour of the day in last month's protest
Police were called to the protest outside the primary school in the Saltley area of Birmingham
The school started its programme four years ago and says it should welcome people who are lesbian, gay, bisexual or transgender
Parents said teaching about LGBT equality at the school is an exploitation of child innocence
Some of the parents said they were not against homosexuality but accused the teacher of promoting 'personal beliefs'
'Brothers and sisters, is it OK for your children to be gay?
'Are you aware of the resource being used in literacy lessons promoting homosexuality?
'Did you know Mr Moffat left his last role because parents believed he had
no right coming out to children? They wanted all the lessons containing LGBT to be removed from curriculum.
'Did you know that our children are now being taught the very same thing?
'Have you asked what your children are being taught? What they are reading?
'Please join us in our petition to have the No Outsider removed from the curriculum.
'Please help us make a difference to what children are being taught.'
Parents' anger is aimed at the school's assistant head Andrew Moffat, who is behind the No Outsiders lessons.
