The jihadist website should of course not be taken at face value. They may well be full of it. I would be surprised if jsome jihadists aren’t responsible though.
There’s a Wikipedia entry on the bombings. They are generally very useful with these sort of events, distilling, summarizing all relevant info.

Of course not, and after my mess-making on the March 11 one, I won’t stick my neck out this time. We await information. I think the claim though is part of the relevant information. And the similarities with Madrid are rather striking. Again there are rumours that the bomb on the bus was a suicide bomber, but this is still a rumour and may not be confirmed.
