The World Health Organization (WHO) has voiced deep concern over a potential nuclear disaster as tensions escalate among Iran, the United States, and Israel in the Middle East. WHO’s Eastern Mediterranean Regional Director, Hanan Balkhy, told Politico that the organization is preparing for possible radiation risks and warned that any such incident would have catastrophic consequences. She said that while preparations are underway, the damage could not be fully prevented and its effects might last for decades.

The report notes that the United States possesses the world’s largest nuclear arsenal, while Israel, though not officially acknowledging it, is regarded as the only nuclear-armed state in the region. According to the International Atomic Energy Agency, Iran has not yet enriched uranium to weapons-grade levels, though its nuclear program remains a source of long-standing concern. In June last year, the United States carried out strikes on Iran’s Natanz, Isfahan, and Fordow nuclear facilities, which President Donald Trump claimed were “completely destroyed.”

Balkhy cited the 1945 atomic bombings in Japan and the 1986 Chernobyl disaster as examples of long-term health and environmental impacts. WHO is currently advising governments on preparedness measures, though details of its guidance have not been disclosed.
