A small explosion in Kosovo is quickly growing into a much bigger incident after the authorities in the capital, Pristina, arrested three Germans, alleged to be intelligence operatives, in connection with an attack on the building that houses the European Union’s special representative there.

A judge in Kosovo remanded the three men – who media outlets there and in Germany have reported are members of the German foreign intelligence agency, the BND – to 30 days of investigative custody Saturday. On Monday in Berlin, a government spokesman, Thomas Steg, called the charge that Germany was involved in terrorist attacks abroad “absurd,” but declined to comment on whether the men were intelligence agents or, as has also been alleged, members of the German Army, the Bundeswehr.
