Stockholm, Aug 9 (DPA) The European Union (EU) Saturday protested over the trials in Tehran of some 100 opposition supporters, expressing concern and demanding that all those bing held be freed.

The protest was issued by the current Swedish presidency of the EU Council of Ministers.

The protest said the EU would view any act by Iranian authorities against one of its members as an act against the whole EU, which would react accordingly. The statement made no mention of specific measures.

Swedish Foreign Minister Carl Bild indicated in his internet blog that the diplomatic reaction followed telephone consultations with his counterparts in Britain, France and Germany.
