A CNN post says that authorities broke up a bomb plot in Amsterdam. The plot was allegedly aimed at heavily trafficked public areas. The article reports that one of the 7 cell members apprehended has connections to a bombing in Madrid. It is not clear from the article whether that bombing is the train bombings in Madrid or something else.
If the connection between this plot and the train bombings is true then everyone has reason to be concerned. This is clear evidence that terrorist cells are still targeting public areas in large Western cities. I believe it is especially important because I think we have lost focus on the fact that terrorists are still aiming for us, and that the threat is real and affects us right now.
