Iran summons German envoy over EU condemning dissident's execution
The EU in a statement on Saturday condemned the execution in the "strongest terms" and emphasised its "irrevocable opposition to the use of capital punishment".
The Iranian foreign ministry's Europe director in turn told Germany's ambassador, Hans-Udo Muzel, that Tehran "condemned" the statement, which it deemed "an unacceptable interference in Iran's domestic affairs," state news agency IRNA said.
Germany currently holds the European Union's rotating presidency.
IRNA also reported Sunday that the foreign ministry will summon the head of France's embassy in Tehran.
Iran also protested the "indulgence towards elements spreading violence and committing terrorist acts" against Iran shown by "some European countries," it added.
Zam was granted political asylum in France and reportedly lived in Paris before his arrest last year by Iran's Revolutionary Guards, who claimed he had been "directed by France's intelligence service."
The EU's External Action Service had also said Saturday "it is... imperative for the Iranian authorities to uphold the due process rights of accused individuals and to cease the practice of using televised confessions to establish and promote their guilt".
France's foreign ministry had likewise decried the hanging, calling it "an unacceptable and barbaric act" and a "serious attack on freedom of expression and freedom of the press."
Zam was charged with "corruption on earth", one of the most serious offences under Iranian law.
IRNA also said he was convicted of espionage for France and an unnamed country in the region, cooperating with the "hostile government of America", acting against "the country's security", insulting the "sanctity of Islam" and instigating violence during protests in 2017.
At least 25 people were killed during the unrest in December 2017 and January 2018 that was sparked by economic hardship.
