How do we deal with not just the acts of violence, but the extremist ideology that lies behind them? Because though the numbers of fanatics that go and join and kill for a group like ISIS are measured in tens of thousands, those that support the wider ideology, I'm afraid, you measure in tens of millions or more.

As for those that carried out these attacks there are no adequate words of condemnation. Their barbarism will stand as their shame for all eternity.
