If I may, I will make a little progress.
Our response to that threat is and will remain measured, deliberate and comprehensive. At home, our police and security agencies are hard at work tackling the threat from returning jihadis and intercepting those intent on travelling abroad to join ISIL. Since April 2013, 23 people have had their passport removed and so far this year 69 people have been arrested for terror-related offences in relation to Syria and Iraq.
As the Prime Minister set out last week, we are now urgently considering what more we can do in the face of this unprecedented terrorist threat. Among the measures being actively considered by the Government are strengthening the existing terrorism prevention and investigation measures, including through stronger location constraints on suspects and a requirement on individuals to engage with the Prevent programme; putting the Channel de-radicalisation programme on a statutory footing; introducing temporary powers for police to seize passports at the border while suspected foreign fighters are investigated; creating a discretionary power to exclude British nationals from the UK; and putting on a statutory basis aviation security measures, including no-fly lists and the sharing of passenger information. As the Government crystallise our proposals, the House will have the opportunity to debate them in detail.
Strengthening our defences at home and tackling the movement of foreign fighters are just part of the answer. We must also tackle these threats at source, so we are responding to the urgent humanitarian situation in the region, alleviating suffering in northern and eastern Iraq and helping to ease the growing burden on the neighbouring states that has the potential to create even greater instability. Since the crisis in Syria began, we have committed more than £600 million in humanitarian aid. In northern Iraq, Britain was the first donor country on the ground, but we are clear that alongside the immediate humanitarian response there must also be a coherent political response to delegitimise ISIL, cut off its sources of financial support and create the conditions under which local forces can regroup and tackle ISIL head on.
