The World Health Organization (WHO) is preparing for a potential “nuclear incident” in the Middle East, as escalating tensions between Israel and Iran raise concerns about the possible use of nuclear weapons or an attack on a nuclear facility. The warning comes as the conflict, which began on February 28, has already seen attacks on nuclear sites within Iran, though no radioactive contamination has been reported to date. This growing crisis is prompting international health officials to consider worst-case scenarios and prepare for consequences that could extend for decades.
Hanan Balkhy, WHO Regional Director for the Eastern Mediterranean, expressed deep concern about the situation, telling Politico that the “worst-case scenario” involves either a direct attack on a nuclear facility in Iran or the use of nuclear weapons by one of the involved parties. She emphasized that even with extensive preparation, the region would be unable to fully mitigate the devastating effects of such an event. The WHO is bracing for a range of potential fallout, acknowledging the immense challenge of responding to a nuclear incident.
Escalating Conflict and Nuclear Concerns
The current escalation of conflict has already placed significant strain on health systems across the Middle East, as reported by the WHO on March 11, 2026. Iran has reported over 1300 deaths and 9000 injuries, while Lebanon has seen at least 570 deaths and more than 1400 injuries. Israel has reported 15 deaths and 2142 injuries. Beyond the immediate casualties, attacks on healthcare facilities are hindering access to vital medical services. The WHO has verified 18 attacks on healthcare in Iran and 25 in Lebanon since February 28, resulting in deaths of health workers in both countries.
Adding to the complexity, Israel is widely believed to possess undeclared nuclear weapons, while Iran maintains its nuclear program is for peaceful purposes. Concerns have been raised about the potential for escalation, particularly after a recent assessment by David Sacks, a former advisor to US President Donald Trump, who suggested Israel might consider using a nuclear weapon if its air defenses were overwhelmed. While President Trump dismissed these concerns, stating “Israel wouldn’t do that,” the possibility remains a subject of international anxiety.
Recent Attacks and International Response
The situation took a concerning turn earlier this week when Iranian authorities reported a strike near the Bushehr nuclear power plant. Aleksey Likhachev, director general of Russia’s state nuclear corporation Rosatom, condemned the attack as a “flagrant disregard for the key rules and principles of international security.” Rosatom confirmed that no casualties were reported and radiation levels remained normal, but the incident underscores the heightened risk to nuclear infrastructure in the region.
Russia’s Foreign Ministry spokesperson, Maria Zakharova, echoed these concerns, condemning the strike as “irresponsible and absolutely unacceptable” and calling on both Tel Aviv and Washington to cease attacks on nuclear facilities to prevent a potential “radiological and environmental catastrophe” on a regional scale. Russia’s condemnation highlights the international community’s growing alarm over the potential for a wider conflict.
Preparing for the Unthinkable
The WHO’s preparations for a potential nuclear incident are multifaceted, encompassing planning for both immediate response and long-term health consequences. The agency is considering the logistical challenges of providing medical care in a contaminated environment, as well as the potential for widespread displacement and public health crises. The organization is similarly working to strengthen surveillance systems to detect and respond to any release of radioactive materials.
The potential for a nuclear incident in the Middle East carries implications far beyond the immediate region. The consequences of such an event could include widespread environmental contamination, long-term health effects, and significant geopolitical instability. The WHO’s warning serves as a stark reminder of the urgent demand for de-escalation and a renewed commitment to diplomatic solutions.
Looking Ahead
As the conflict continues, the international community is closely monitoring the situation for any signs of further escalation. The next key development will likely be the response from Iran to the recent attacks on its nuclear facilities and the ongoing diplomatic efforts to de-escalate tensions. The WHO continues to assess the evolving situation and refine its preparedness plans, emphasizing the importance of preventing a nuclear incident at all costs. The agency will provide further updates as the situation develops.
