re: Massive arrests in France
I have no information on the group People's Mujahideen, but it's interesting that the EU declared them terrorists in 2002 and France is only now moving against them. Some people suspect it has less to do with terrorism and more to do with them being an exile group opposed to the Mullah dictators of Iran. France has a history of sucking up to dictators.
Here's a link to a more detailed article.
