Evidence mounts of the breadth of terror cells in Europe

CBS News:

In the wake of the bombings in Belgium this week -- and increasing criticism of officials for their inability to thwart those attacks -- police in the last 24 hours have made at least four arrests in a series of raids in Belgium and four other countries across Europe.
New evidence shows disturbing evidence of just how big the terror network is across Europe.

CBS News' Allen Pizzey reports from Brussels that, as the effort to break the terrorist cell that carried out the bombings goes on, Belgian officials are coming under increased scrutiny and criticism for what is being seen as a series of intelligence failures.

In an operation that played out in full view, Belgian police shot a man who was spotted with a suspicious bag at a tram stop Friday.

The raids have uncovered what is being described as "alarming" evidence of a Europe-wide jihadist cell connected to the attacks in Belgium as well as those in Paris in November.

Belgium is still coming to grips with the various plots and chasing down leads.   It still needs more resources dedicated to the fight and it needs greater cooperation between intelligence operations and law enforcement.  It probably needs to mobilize military units to protect key infrastructure like its nuke plants.
