A Dutch newssite mentioned Al-Quaeda, but it's so early on to say anything about that, I guess.. though they are the usual suspect, yeah.

edit: this is a quick translation of two snippets I read on that dutch newssite (nu.nl)

"Arab sources which keep close tabs on the Al-qaeda network, have told the BBC that the explosions might be the work of Osama binLaden's network.

According to an Israeli radiostation, Israel was warned on thursday a few hours before the attack by Scotland Yard to increase security and to be extra alert."
