Terrorist Attacks (Paris)

In his evidence at Westminster yesterday, the director of Europol spoke of a security gap among police forces across Europe in trying to track down online terrorists. Terrorism has no national boundaries. Is the Home Secretary confident about the structures that currently exist for the sharing of information across Europe, and indeed across the Atlantic? What further action can the internet companies take? Should we not now consider having an organisation similar to the Internet Watch Foundation to deal specifically with counter-terrorism?
