Switzerland expressed regret on Friday after its ambassador to Iran displayed a cartoon depicting two doves defecating on Prime Minister Benjamin Netanyahu's head, at an event promoting Iranian business opportunities.
Ambassador Giulio Haas showed the image during a speech to hundreds of Swiss and Iranian business people at a Zurich hotel on Thursday.
The Swiss Federal Department of Foreign Affairs (FDFA) said the "questionable cartoon" was used without its knowledge. "The FDFA regrets the use of this cartoon and considers it tasteless," it said in a statement.
Haas' address came as Europeans race back to Iran, whose markets and major reserves of oil and gas will be much easier to tap once sanctions are lifted under a global deal struck last month.
