Is Europe becoming a base for terrorist?

Is Europe becoming a platform for terrorists?

One of the biggest threats to US security may now come from within Europe, US Homeland Security head Michael Chertoff has told the BBC. Do you agree?

He said militant attacks and plots in Europe over recent years had made the US aware of the "real risk that Europe will become a platform for terrorists".

Mr Chertoff said it was likely security checks on travellers from Europe would be increased.

He cited deadly bomb attacks on Madrid and London, and a terror alert affecting UK-US flights in August 2006, as well as "people travelling from South Asia and the Middle East into Europe and carrying out attacks there".

How serious is the terrorist threat from within Europe? Do you think security measures need to be improved? Have you a personal experience of being affected by increased security measures?
