Iranian Missile Strike Devastates Weizmann Institute, Israel’s Scientific Powerhouse

REHOVOT, Israel — The Weizmann Institute of Science, a cornerstone of Israel’s technological innovation and a global leader in scientific research, was left in ruins following a barrage of Iranian ballistic missiles on June 15, 2025. The attack, part of an escalating conflict between Israel and Iran, caused catastrophic damage to laboratories, data centers, and decades of irreplaceable research, with estimated losses exceeding $500 million. The institute, often regarded as a critical asset to the Israel Defense Forces (IDF) for its advancements in AI, military technology, and biomedical research, now faces an unprecedented setback.

The strikes, which hit Rehovot in the early hours of Sunday, targeted the institute’s 280-acre campus, reducing entire buildings to rubble and setting laboratories ablaze. According to Ynetnews, two missiles scored direct hits, destroying a life sciences facility and an unfinished chemistry building, while damaging dozens of other structures. Approximately 45 laboratories were affected, with researchers reporting the loss of vital equipment and biological samples accumulated over decades. Professor Alon Chen, president of the Weizmann Institute, described the devastation: “The missiles completely erased decades of research; we will need to start from scratch.”

The Weizmann Institute has long been a symbol of Israel’s scientific prowess, contributing to breakthroughs in cancer research, artificial intelligence, and military technologies such as drone systems and encryption tools. Its collaborations with the IDF have made it a strategic asset, with some speculating this role rendered it a deliberate target for Iran’s retaliatory strikes. Euronews reported that the institute’s work on advanced military systems, including AI for combat guidance and nuclear energy applications, may have drawn Tehran’s attention following Israeli attacks on Iranian nuclear facilities.

The human toll, while miraculously limited, was deeply felt. No fatalities were reported on campus, but 42 people were injured in surrounding Rehovot, where residential areas and a train station also sustained damage. The New York Times quoted Alan Monziani, a PhD student residing in campus dormitories, who witnessed the destruction: “One side of the cancer research center was missing most of its walls — it was hard to tell whether it took a direct hit or was struck by shrapnel, because it was engulfed in flames.”

The scientific community is reeling from the loss. Professor Eldad Tzahor, whose regenerative medicine lab was obliterated, described the scene as a “war zone,” with 22 years of heart tissue and DNA samples destroyed. Science|Business reported that 90% of the institute’s buildings sustained some form of damage, disrupting around 15 European Research Council-funded projects and forcing 44 of the institute’s 270 research groups to seek new facilities. The financial cost is staggering, with internal estimates suggesting $500 million for repairs alone, though researchers emphasize that the loss of knowledge is incalculable.

SNN released footage on June 19, revealing the extent of the destruction: charred walls, shattered windows, and exposed wiring amid flooded labs from firefighting efforts. The Times of Israel noted that the attack not only gutted physical infrastructure but also erased years of national advantage, as the institute’s contributions have long bolstered Israel’s technological edge.

In the wake of the attack, Weizmann’s leadership vowed to rebuild. Professor Chen, a brain scientist, expressed resilience: “We are the best at generating outstanding knowledge for the future of humanity, and we will continue to do so.” Yet, the road ahead is daunting. The Jewish Chronicle highlighted the destruction of the institute’s pioneering cancer research center, underscoring the global implications of the loss.

The strike marks a grim chapter in the Israel-Iran conflict, which intensified after Israeli attacks on Iranian nuclear sites and military targets. As both nations exchange blows, the targeting of a civilian research institution raises questions about the broader costs of this escalating war. For now, the Weizmann Institute stands as a symbol of both Israel’s scientific ambition and the fragility of progress in the face of conflict.
