I don't know where to start with this thing. First, it's totally unsourced. It says, "A British police dragnet has raised suspicion..." but doesn't tell us who is holding that suspicion. It says (in the hed, which probably wasn't written by the reporter) "Police fear..." but never tells us who told the reporter. But let's check the substance.
Police fear that terror suspects arrested in Denmark are linked to a British plot to attack the US White House
A British police dragnet has raised suspicion that nine terrorist suspects arrested in Denmark and Bosnia are linked to a plan to attack the White House and other strategic targets in the United States.
British police became interested in one of the suspects after they arrested three men in London and found they had had email correspondence with a man living in Bosnia. The man living in Bosnia had been suspected of running a network that sought to draw alienated youths to the rebellion in Iraq.
Seven 16-20-year-olds are currently under arrest in Denmark along with two 18-year-old men in Sarajevo, one of Danish-Turkish heritage and the other from Sweden, in connection with the find of cache of weapons and explosives in Sarajevo.
Two days after the two were arrested in Sarajevo, British police arrested three people in Great Britain on suspicion of planning a terror attack on The White House.
The three men had apparently been in email correspondence with someone in Sarajevo who used the codename 'Maximus'.
Police in Denmark and Bosnia arrest a bunch of people. Then the Brits arrest three more folks, apparently in an investigation that was at first unrelated. They find that
The sole connection between the UK arrests and those in Denmark and Bosnia seems to be this 'Maximus' guy -- but the article doesn't even tell us whether those arrested in Denmark and Bosnia were ever in touch with him!
I'm not denying the very real danger of radicalism in Bosnia, or the potential for terrorism there. But the fact is that all of it is so far just speculation -- and I hope it'll remain that way.
