According to Israel, Iran has intensified efforts to target Israeli and Jewish sites worldwide since the Hamas-led attack on Israel on October 7, 2023.
The statement said that attempted attacks in Germany, Greece and Australia had been thwarted this year and last year with Mossad's assistance.
The man allegedly responsible was named as Sardar Amar, described as a senior commander in Iran's Islamic Revolutionary Guard Corps (IRGC).
"Under Amar's command, a significant mechanism was established to promote attacks against Israeli and Jewish targets both in Israel and abroad," the statement said.
"This mechanism is directly responsible for the attempted attacks exposed in Greece, Australia and Germany in the past year alone, and its numerous failures led to the wave of arrests and its exposure."
The Australian government expelled Iranian ambassador Ahmad Sadeghi in August after ASIO said it had "credible evidence" the IRGC directed at least two attacks on Jewish premises through connections with domestic criminal elements.
The Adass Israel Synagogue in Melbourne was one of the sites firebombed by criminal proxies in December 2024, badly damaging the building and injuring a worshipper.
The other site targeted was the Lewis' Continental Kitchen in Sydney, a kosher deli and a mainstay of Bondi in the city's eastern suburbs, which was firebombed in October.
German prosecutors in June revealed that a Danish citizen in Berlin was suspected of spying on Jewish individuals and institutions as well as sites linked to Israel on behalf of Iranian intelligence.
The 53-year-old man, of Afghan origin, was later arrested in Aarhus, Denmark.
Prosecutors said the surveillance may have been intended to prepare for attacks.
Iranian authorities rejected the allegations about involvemnet in the incidents in Australia and Germany as unfounded.
The Iranian embassy in Berlin said the claims were part of a campaign to distract from Israel's war with Iran in June.
