The European Union presidency said on Saturday it was concerned at a trial in Iran involving employees of the British and French embassies, and that action against any EU embassy staff was action against all of the EU, Reuters reported.
"The presidency expresses its concern over the ongoing trial in Tehran in the aftermath of the election, including against two EU member states' embassy employees and one EU citizen," the statement by the EU's Swedish presidency said.
"The presidency reiterates that action against one EU country, citizen or embassy staff, is considered an action against all of the EU".
