Odd stuff in Kosovo

The fact that several thousand Kosovars paraded in Pristina against the imposition of the EU police force that will from December 9th run the country is one thing, but this little story from a week or so ago is really strange,

"PRISTINA, Nov 22 (Reuters) - Germany declined to comment on Saturday on reports that three Germans arrested on suspicion of throwing explosives at an EU office in Kosovo were intelligence officers.
The explosive charge was thrown on Nov. 14 at the International Civilian Office (ICO), the office of EU Special Representative Pieter Feith, who oversees Kosovo's governance, but caused only minor damage. The men were detained on Thursday.
A spokesman for the German foreign ministry in Berlin confirmed that three Germans had been arrested, but declined to make any further comment as an
investigation was under way.
A police source in Kosovo told Reuters: "They are members of the BND", but gave no further details. The German weekly Der Spiegel also said the men worked for the German intelligence agency BND, and that they had told investigators they had been examining the scene of the explosion, but had not been involved in it.
Kosovo declared independence from Serbia in February after nine years under U.N. stewardship and is recognised by more than 50 countries, including Germany.
Four days before the bomb attack, its leaders rejected a plan by U.N. Secretary General Ban Ki-moon's for the deployment of an EU police and justice mission, EULEX.
Der Spiegel said the BND agents had not been officially registered with Kosovo authorities, which would have secured them diplomatic immunity.
A judge in Pristina was due to decide on Saturday whether to extend the men's detention or release them on bail.
