Why was Rouzbeh Vadi arrested and killed?

Iranian officials say that Vadi gave important information about Iran's nuclear activities to Israeli intelligence. The court says he gave Mossad handlers information about fellow scientist Ahmad Zolfaghari, who was killed during the June war. Iranian intelligence kept an eye on him and arrested him in Tehran, allegedly after he met with Mossad officers in Vienna several times.

The court found him guilty of "hostile acts against peace and security" under Article 6 of Iran's law and sentenced him to death, saying he had committed serious crimes against national and international stability. The Supreme Court turned down his appeal.

How did Mossad supposedly hire and train him?

Iran's courts gave a detailed description of how they hired Vadi: an agent using the name "Alex" reportedly contacted him online and checked him out. Later, he met a handler named "Kevin," and Mossad is said to have marked him as a high-value source because of his job and access.

Authorities say that Mossad sent Vadi to Vienna with strict security, where he took a polygraph test and had psychological evaluations.

Vadi learned about safe ways to talk to people in five different meetings and was told to report on nuclear issues within the organization on a regular basis. Iranian officials say that the payments were sent every month through crypto wallets, as per a report by Iran International.

Officials say that even though Vadi was hesitant at first to send large amounts of data, he eventually did give up sensitive information, including information about scientists who had been killed.

Why is Iran so strict about spying?

Vadi's execution is part of a larger crackdown after the war. Since the June war between Iran and Israel, more than 2,000 people have been arrested. Many of them are accused of helping enemy states or spying on them online and in person. Gholamhossein Mohseni Ejei, the head of Iran's judiciary, has promised "decisive" punishment for traitors, and human rights groups are sounding the alarm.

Amnesty International and Iran Human Rights say that Iran will carry out more than 60% of the world's executions in 2024. There were 612 executions reported in the first half of 2025. At least six people have been charged with spying for Israel in the recent rise.

One of them was Mohammad-Amin Mahdavi-Shayesteh, who was accused of being the leader of a cyber group linked to Mossad. The rising number of deaths has raised concerns around the world. Critics warn of secret trials, vague charges, and a scary environment for academics and political dissidents, as per a report by Iran International.

The death of Rouzbeh Vadi is the most recent and most well-known example of how Iran is tightening its grip on national security.
