BERLIN - Germany said on Tuesday it had summoned Iran's ambassador to reprimand Tehran against spying on individuals and groups with close ties to Israel, calling such acts a completely unacceptable breach of German law. The move comes after the March conviction of a Pakistani man for spying for Iran in Germany went into force. Mustufa Haidar Syed-Naqfi was convicted of gathering intelligence on Reinhold Robbe, the former head of the German-Israel Friendship Society, and an Israeli-French economics professor in Paris, for Iran's elite Revolutionary Guards.
