Today is the third day of official mourning in France. The attacks in Paris initially left me speechless. As a journalist I have covered terrorism for many years. I travelled across Afghanistan, Africa and South East Asia to understand how the world fights Al Qaeda and Jemaah Islamiya. At some point, I decided to quit that dangerous game. Now, terrorism has caught up with me. The train to Paris takes barely two hours. The Islamic State has struck in the heart of Europe, the City of Light. I would not have thought this group of fanatics able to mount simultaneous attacks of such violence in Europe.
