My hon. Friend is right. It is important that we make very clear the dangers and the horrors of what can happen when people go to such countries. Even if people are going to Syria with the best of humanitarian intentions, they can find themselves caught up in horrific situations, including with terrorist groups. That message is important. We have consistently been saying to people that they should not be travelling to Syria and Iraq. If they wish to help and support the people of Syria who have been displaced by the actions of the regime in Syria, there are better ways of doing it. That is a message that we will continue to put out.
