Isis has now claimed responsibility for the Brussels terror attacks in which at least 30 people have been killed and scores more injured.
But although the so-called Islamic State means Syria is the current focus for so many people, we shouldn’t think that Syria is the only source of terrorism.
Belgium has become the hub of Islamist terror groups.
Most of them are of a North African background; they come from Morocco, Algeria, Tunisia and a huge number have gone and fought in Syria, a lot of them with Isis.
How many terror cells are there? We don’t know how many.
There has obviously been a failure of intelligence in France and there has not been adequate liaison.
People say that if we leave the EU, then the terror threat will grow. But we can see the two countries side by side with a lack of intelligence being shared.
