Mousavian was Iran's Ambassador to Germany from 1990 to 1997. Four Iranian dissidents were murdered at Berlin's Mykonos restaurant in 1992, and five years later a German court concluded that Iran's Special Affairs Committee had ordered the murders, and that the supreme leader, president, foreign minister and intelligence minister of Iran were all active members of that committee. The court found an Iranian intelligence officer and three Lebanese men guilty and issued an arrest warrant for Iran's intelligence minister. Also, Germany expelled four Iranian diplomats and asked that Mousavian be recalled to Iran; he did return to Tehran shortly thereafter. After the issuance of the arrest warrant for the intelligence minister, which Mousavian described as an insult to the entire population of Iran, Iranian news agencies made veiled threats against Germans abroad. Mousavian echoed, saying that if European nations kept treating Iran as America and Israel did, then they would be treated the same way by Iran.
