In June 2025, Israeli strikes killed several top Iranian commanders and six nuclear scientists, targeting nuclear facilities, ballistic missile factories, and military leaders to prevent Tehran from developing an atomic weapon. In response, Iran has moved about 15 of its remaining 100 nuclear scientists into hiding, according to The Telegraph.
These researchers have been relocated to secure locations in Tehran or northern coastal cities. They no longer live at home or teach at universities, instead residing in guarded villas with their families. “Those who were teaching at universities are replaced with people who have no connection with the nuclear programme,” an Iranian official revealed.
New Generation of Scientists Under Constant Threat
Israeli briefings have warned of further assassinations, including the execution by Iran of one of its scientists over alleged collaboration with Israel. Israeli experts say the newly promoted scientists are “dead men walking,” despite round-the-clock protection and safe houses.
Many of these scientists are believed to be working at Iran’s Organisation of Defensive Innovation and Research (SPND), specialising in explosives, neutron physics, and warhead design.
Israeli intelligence analyst Ronen Solomon explained, “While the eliminated scientists focused more on warhead design, the expertise in delivery systems makes those who remain equally strategic targets for Israel, as Israel’s June 2025 strikes also targeted ballistic missile infrastructure.”
Israel’s Stance: Every Scientist Is a Target
Danny Citrinowicz, former head of the Iranian strategic desk in Israeli Defense Intelligence, said:
“Those who are left will be at the forefront of any Iranian attempt to reach a nuclear bomb, hence they will automatically become targets for Israel… Any scientist that deals with the nuclear issue will be eliminated or will be threatened with elimination.”
Security Reinforced Amid Trust Issues
Security for the scientists has been significantly strengthened. Previously, a single Revolutionary Guard unit handled their protection, but multiple agencies are now involved due to trust concerns. “They were all asked if they still trust their bodyguards — some said no and were provided with new ones,” an Iranian official confirmed.
Casualties of the Conflict
The June conflict left over 620 people dead in Iran, including 12 scientists and 20 senior commanders, with 4,870 injured. Iranian retaliation killed 28 people in Israel and injured more than 3,000.
