Per Sky News, the men are of north African origin.

They were arrested after an operation by the anti-terrorist branch in north and east London on Sunday.

Disregard my last, I missed the Skynews article somehow in the thread. For the fella that didn't know about the assassination using ricin and umbrella... watch the history channel more often! :) They had a whole show on that once, and by the way, it might have been "Bulgarian Secret Police" that carried it out, but they were under the USSR in those days, and in fact that method was created by the KGB themselves to use in assassinations plots. That is the only know assassination that HAS occurred using that method to my knowledge.

I'm not sure whether or not ricin can be used in another modes, or whether it must be given subcuteanously or not. If it can be ingested directly then posioning water would be a 'viable alternative'.
