Police in New Delhi have reportedly concluded that terrorists belonging to a branch of Iran’s military were behind a February 13 bomb attack on the wife of an Israeli Embassy worker.

The Times of India reported Monday that Indian officials believe members of the Iranian Revolutionary Guards were behind the attack, and may have planned other attacks on Israeli targets around the world in revenge for the killings of Iranian nuclear scientists, which Tehran has blamed on Israel.

The report noted the police have sent the information to Iran in a request to cooperate with the investigation.

Officials have long suspected Iranian involvement in the Delhi attack, which injured Tal Yehoshua Koren, wife of the Israeli military attaché, as well as other attempted and successful attacks, including a bus bombing in Burgas, Bulgaria, earlier this month that killed five Israelis and a Bulgarian bus driver.

While Indian officials have already said Iranian elements likely had a role in the bombing, the police conclusion is the strongest evidence yet that the attacks were ordered by Tehran’s political leadership.

According to the report, Indian-Iranian journalist Syed Mohammed Kazmi was in touch with a number of members of the Revolutionary Guard for almost 10 years, and began discussing ways to avenge the nuclear scientist killings in January 2011.

One of the men he was in touch with, Masoud Sedaghatzadeh, is alleged to have engineered attempted attacks in Tbilisi, Georgia, and Bangkok ,Thailand, as well. Both attacks were thwarted at the last moment.

Police also believe a woman, identified as Leila Rohani, had a role in the three attacks, though she is since believed to have fled to Iran. She is thought to have helped the Iranian would-be attackers rent a room in Bangkok.

Israel and Iran have been locked in a cold war for several years, with Jerusalem warning of the dangers of Iran gaining nuclear capability and threatening military action. A recent book pointed to Israeli involvement in the killings of several Iranian nuclear scientists, though Israel has never admitted any role in the deaths.

Israeli officials have pointed to Iran, and its proxy Hezbollah, as behind a number of attempted attacks on Israeli and Jewish targets around the world. Two Iranians were recently arrested in Kenya for plotting to blow up a synagogue and the Israeli Embassy in Nairobi, and a plot to attack Israelis in Cyprus was also foiled earlier this month.
