Young Muslims in Britain are being drawn into terrorism by ISIS videos which have turned violent murderers into celebrities, David Cameron will claim today.

The Prime Minister will use a major speech to warn the 'barbaric realm' of the terror group can seem 'exciting' to young people who do not feel a connection to Britain.

The government is planning a major crackdown on non-violent extremism which acts as the gateway to radicalisation and a 'cultish attachment to death'.

Speaking out: David Cameron will make his speech in Birmingham and is hoping to highlight the 'failures of integration' in parts of the UK

At least 700 people from the UK have travelled to Iraq or Syria to join ISIS – also known as Islamic State, ISIL and Daesh.

Mr Cameron will say that many of them have found a 'sense of belonging that they can lack here at home'.

And he will condemn Muslim conspiracy theorists who seek to excuse attacks launched by jihadist groups with claims about 9/11 and the 7/7 bombings in London.

A failure of integration means that some young Muslims 'don't really identify with Britain and feel little or no attachment to other people here',' he will say.

'Indeed, there is a danger in some of our communities that you can go your whole life and have little to do with people from other faiths and backgrounds.'

'So when groups like ISIL seek to rally our young people to their poisonous cause, it can offer them a sense of belonging that they can lack here at home, leaving them more susceptible to radicalisation and even violence against other British people to whom they feel no real allegiance.'

ISIS have continued to produce slick propaganda videos, designed to entice young Muslims to leave their homes and join the jihad in Syria and Iraq

9/11 HAPPENED BEFORE IRAQ WAR: CAMERON TACKLES CONSPIRACIES David Cameron will today reject the 'grievance justification' that some use to explain the rise of jihadist terorrism. The Prime Minister will tackle head on claims that the 2003 Iraq War, recent wars and poverty are responsible for recruiting people to the cause of groups like ISIS and al Qaeda. Mr Cameron will say: 'Let's not delude ourselves. We could deal with all these issues and some people in our country and elsewhere would still be drawn to Islamist extremism,' he will say. 'No, we should be clear: the root cause of the threat we face is the extremist ideology itself.' He will add: 'When people say “it’s because of the involvement in the Iraq War that people are attacking the West”, we should remind them: 9/11 – the biggest loss of life of British citizens in a terrorist attack – happened before the Iraq War. 'When they say that these are wronged Muslims getting revenge on their Western wrongdoers, let’s remind them: from Kosovo to Somalia, countries like Britain have stepped in to save Muslim people from massacres. 'It’s groups like ISIL, Al Qaeda and Boko Haram that are the ones murdering Muslims. 'Others might say: it’s because terrorists are driven to their actions by poverty. But that ignores the fact that many of these terrorists have had the full advantages of prosperous families and a Western university education.' Advertisement

Mr Cameron warns that Britain faces 'a radical ideology' which is 'not just subversive, but can seem exciting'.

'The root cause of the threat we face is the extremist ideology itself. Like any extreme doctrine, it can seem energising, especially to young people.

'They are watching videos that eulogise ISIL as a pioneering state taking on the world, that makes celebrities of violent murderers.

'So people today don't just have a cause in Islamist extremism in ISIL, they now have its living and breathing expression.'

In a stark warning to young people tempted to join ISIS he will add: 'You won't be some valued member of a movement. You are cannon fodder for them. They will use you.

'If you are a boy, they will brainwash you, strap bombs to your body and blow you up. If you are a girl, they will enslave and abuse you. That is the sick and brutal reality of ISIL.

'We must de-glamorise the extremist cause, especially Isil. This isn't a pioneering movement, it is vicious, brutal, fundamentally abhorrent.'

The speech will set out how the government intends to challenge and combat those groups who avoid directly advocating violence but spread 'intolerant ideas' which 'create a climate in which extremists can flourish'.

Mr Cameron will set out plans to target those who stop short of advocating violence, but who influence those who go on the carry out atrocities by spreading an 'extreme doctrine [which] at its furthers end seeks to destroy nation-states to invent its own barbaric realm'.

Mr Cameron will make his speech in Birmingham, a city where local MPs have warned of a 'huge, huge problem' with young people travelling to fight for ISIS.

Mr Cameron will call for a 'stronger, more cohesive country' to counter the dangerous lure of Islamist ideology which he compares to the draw from Fascism and Communism in the 20th Century.

He will launch a review by Louise Casey, a senior civil servant, into how to boost 'opportunity and integration' in Muslim communities, to try and ensure people learn English and to get more women into work.

Mr Cameron will say: 'We need young people to understand that here in the UK they can shape the future by being an active part of our great democracy.

'Achieve this and more people from ethnic minority backgrounds will feel they have a stake in our society.'

Professor Bill Durodié, from the University of Bath, said Mr Cameron needed to 'clarify exactly what it is that people should identify with in Britain'.

He added: 'The evidence points to how the young reject the West prior to looking for something else to believe in. Islam is their motif not their motive.

“Nor should we be fooled into believing that it is some inchoate sense of grievance that drives some out – as opponents of Cameron will propose. If anything, too many are pandered to, perceiving of themselves as victims rather than really being so.

“That too is the expression of a culture that is no longer able to promote itself more positively. If Cameron wants to fix ‘Broken Britain’ as he once did, it is not so much to material inequalities he should look to as to the moral and morale failings that indulge all-manner of malcontents today.'

Last year a Birmingham MP claimed as many as 2,000 Britons are fighting alongside Islamist militants in Syria and Iraq.
