Attack on Renowned Scientific Hub Disrupts Decades of Research Amid Escalating Israel-Iran Conflict.
On June 15, 2025, an Iranian missile strike targeted the Weizmann Institute of Science in Rehovot, Israel, causing extensive damage to multiple laboratories and disrupting years of critical research. The attack, part of a broader barrage of Iranian ballistic missiles and drones, marks a significant escalation in the ongoing conflict between Israel and Iran, with the institute—widely regarded as Israel’s “crown jewel of science”—emerging as a symbolic and strategic target. No casualties were reported on campus, but the strike has dealt a severe blow to Israel’s scientific community, raising concerns about the targeting of intellectual and research assets in the intensifying regional conflict.
The Weizmann Institute, established in 1934 and renamed after Israel’s first president, Chaim Weizmann, is a global leader in scientific research, known for its contributions to life sciences, physics, chemistry, and computer science. The institute, which houses approximately 2,500 researchers and staff, has produced a Nobel laureate in chemistry and three Turing Award recipients, and it built Israel’s first computer in 1954. The strike damaged two key buildings: one housing life sciences laboratories and another under construction for chemistry research. Dozens of other structures on the 280-acre campus sustained collateral damage, including shattered windows, collapsed ceilings, and charred walls, with some laboratories described as “literally decimated.”
The attack is seen as a retaliatory response to Israel’s recent strikes on Iranian nuclear facilities and the assassination of Iranian nuclear scientists and military commanders, which began on June 12, 2025. Professor Oren Schuldiner, whose molecular cell biology and neuroscience laboratory was destroyed, called the strike a “moral victory” for Iran, noting that it targeted “the crown jewel of science in Israel.” The loss of irreplaceable research materials, including heart tissue samples, DNA archives, and specialized equipment, has set back scientific progress by years, with some estimates suggesting rebuilding could cost tens of millions of dollars and take at least two years.
The Weizmann Institute’s ties to Israel’s defense establishment, including collaborations with companies like Elbit Systems on technologies such as artificial intelligence, drones, and cybersecurity, may have made it a strategic target for Iran. Yoel Guzansky, a senior researcher at the Institute for National Security Studies in Tel Aviv, suggested that Iran likely intended to strike the institute, viewing it as a symbol of “Israeli scientific progress.” He noted that the attack reflects Iran’s intent to retaliate for Israel’s targeting of its own scientists, stating, “You harm our scientists, so we are also harming your scientific cadre.” In 2024, Israeli authorities uncovered an Iranian plot to assassinate a Weizmann scientist, underscoring the institute’s prominence in Iran’s strategic considerations.
The strike has had a profound impact on the Weizmann community. Professor Eldad Tzahor, a 22-year veteran of the institute’s molecular biology department, reported the complete destruction of his laboratory, which studied heart regeneration. “We had a collection of thousands of heart samples from animals and humans, and nothing remains,” he said, emphasizing the loss of irreplaceable research archives critical for scientific publications. Biologist Jacob Hanna, who was abroad during the attack, learned that his students managed to save hundreds of frozen cell lines by transferring them to backup storage, a precaution taken due to the ongoing regional tensions.
The institute has been closed to faculty and staff since the attack, with visitors evacuated to off-campus hotels. Emergency services are investigating reports of individuals possibly trapped in damaged buildings, though no injuries have been confirmed on campus. The broader Rehovot area was also affected, with at least 42 civilian injuries reported from a separate missile strike on a residential area. The Weizmann administration is working to relocate researchers to shared lab spaces and has pledged to rebuild, with a spokesperson stating, “Together, as a Weizmann community, we will rebuild with renewed resilience and continue our mission to advance scientific discovery.”
The attack comes amid a broader escalation between Israel and Iran, triggered by Israel’s Operation Rising Lion, which targeted Iran’s nuclear and military infrastructure. Iran’s retaliatory barrages have killed at least 24 people in Israel, while Israeli strikes have claimed over 240 lives in Iran, according to official reports. The Weizmann strike has sparked debate about the vulnerability of civilian research institutions in modern warfare, particularly those with dual-use applications. Some researchers, like Professor Sarel Fleishman, whose lab was spared, highlighted the irreplaceable nature of lost materials, stating, “Life sciences labs rely on materials gathered over many years. When a lab is destroyed, it’s not just equipment—it’s irreplaceable.”

The Weizmann Institute’s contributions to global science, from cancer research to artificial intelligence, have solidified its reputation as a world-class institution. The attack threatens to disrupt ongoing projects, including those funded by the European Research Council, which recently awarded six grants to Weizmann scientists.
Iran’s Strategic Retaliation
Iran’s targeting of the Weizmann Institute follows Israel’s strikes on its nuclear facilities at Natanz and Isfahan, which killed key scientists and damaged critical infrastructure. Analysts suggest the attack was a calculated response to Israel’s long-standing strategy of targeting Iran’s scientific community.
Impact on Israel’s Defense Innovation
The Weizmann Institute’s collaborations with Israel’s military, including advancements in drone technology and battlefield medicine, have made it a strategic asset. The strike underscores the risks faced by institutions bridging civilian and military research.
Rebuilding Amid Conflict
Weizmann scientists are already planning to relocate to temporary facilities, but the loss of specialized equipment and data poses significant challenges. The institute’s leadership is coordinating with security and emergency agencies to ensure campus safety and expedite recovery efforts.
Why This Matters
The strike on the Weizmann Institute highlights the escalating Israel-Iran conflict’s impact on civilian infrastructure and scientific progress. The destruction of decades of research not only hampers Israel’s scientific community but also raises questions about the protection of academic institutions in wartime. The attack’s symbolic weight, targeting a cornerstone of Israel’s intellectual and technological prowess, underscores the broadening scope of the conflict, with potential implications for global scientific collaboration and regional stability.
