They knew exactly what they were doing. This is extremely grave.
Na madrugada de 17 de maio, um drone atingiu os sistemas elétricos da central nuclear de Barakah, nos Emirados Árabes Unidos — não por acaso, mas com intenção calculada. O diretor-geral da AIEA, Rafael Grossi, confirmou que os atacantes visavam deliberadamente cortar a alimentação externa do reator, um gesto que poderia ter desencadeado uma catástrofe radiológica de alcance regional. Num momento em que o Médio Oriente absorve milhares de mísseis e drones desde fevereiro, a humanidade confronta uma verdade incómoda: a linha entre conflito convencional e desastre nuclear nunca foi tão ténue.
- Um drone atingiu com precisão cirúrgica os sistemas elétricos de Barakah, revelando que os atacantes conheciam a arquitetura vulnerável de uma central nuclear em funcionamento.
- A AIEA classificou o ataque como 'extremamente grave', alertando que o corte de energia externa poderia ter forçado um encerramento de emergência e uma potencial fuga radioativa.
- Os Emirados Árabes Unidos atribuem o ataque a milícias iraquianas pró-Irão, inserindo o incidente num ciclo de retaliações que já lançou mais de 2.800 mísseis e drones sobre a região desde fevereiro.
- Grossi convocou uma sessão de emergência do Conselho de Governadores da AIEA e percorre o Golfo para avaliar uma ansiedade crescente entre os líderes regionais.
- O pior cenário possível — um ataque direto a Barakah ou à central iraniana de Bushehr — poderia libertar material radioativo através de fronteiras, deslocando populações inteiras e tornando vastas áreas inabitáveis durante anos.
A 17 de maio, um drone atingiu os sistemas elétricos da central nuclear de Barakah, nos Emirados Árabes Unidos. Não se tratou de um disparo perdido. O diretor-geral da AIEA, Rafael Grossi, foi inequívoco: os atacantes sabiam exatamente o que faziam, visando cortar a alimentação externa ao reator — uma manobra que poderia ter desencadeado um encerramento de emergência e, no pior dos casos, uma fuga radioativa. "Isto é extremamente grave", declarou Grossi em Abu Dhabi, após visitar a instalação.
A central de Barakah, construída por um consórcio sul-coreano liderado pela Kepco e operacional desde 2020, fornece cerca de um quarto da eletricidade dos Emirados. Não é infraestrutura menor. O ataque aos seus sistemas de energia foi, na avaliação de Grossi, uma tentativa deliberada de provocar um incidente de consequências catastróficas.
Os Emirados atribuem o ataque a milícias iraquianas pró-Irão, num contexto de escalada regional que se intensificou desde finais de fevereiro, quando Israel e os Estados Unidos iniciaram uma campanha de bombardeamentos contra o Irão. Só os Emirados foram atingidos por mais de 2.800 mísseis e drones. O ataque a Barakah encaixa neste ciclo de retaliações — mas com uma diferença crucial: instalações nucleares não são alvos comuns.
Grossi convocou uma sessão de emergência do Conselho de Governadores da AIEA e percorre o Golfo — Kuwait, Qatar, Arábia Saudita — para auscultar líderes regionais cada vez mais inquietos. O cenário mais temido seria um ataque direto a Barakah ou à central iraniana de Bushehr, que também já foi alvo durante o conflito. Uma rutura de contenção libertaria material radioativo além-fronteiras, afetando milhões de pessoas e tornando vastas áreas inabitáveis durante anos.
O que torna o ataque de 17 de maio particularmente perturbador é a sua precisão: os perpetradores não dispararam às cegas. Miraram o centro nevrálgico de uma central nuclear, apostando numa cascata de falhas. O facto de o diretor da AIEA ter classificado o incidente como "extremamente grave" sugere que a margem entre um incidente contido e uma catástrofe é mais estreita do que muitos imaginam — e que, enquanto o conflito no Médio Oriente persistir, essa margem poderá continuar a estreitar-se.
On May 17th, a drone struck the electrical systems at Barakah, the nuclear power station in the United Arab Emirates. It was not a stray shot in a larger conflict. The International Atomic Energy Agency's director-general, Rafael Grossi, made clear this week that the attackers knew exactly what they were doing. They were trying to knock out external power to the reactor—a move that could have forced an emergency shutdown and, in the worst case, triggered a radioactive release. "This is extremely grave," Grossi told journalists in Abu Dhabi after visiting the plant.
The Barakah facility, built by a South Korean consortium led by the energy company Kepco, began operating in 2020 and now supplies roughly a quarter of the UAE's electricity. It is not a marginal piece of infrastructure. The attack on its power systems was, in Grossi's assessment, a deliberate attempt to provoke what he called an "extremely grave incident"—language that carries weight when spoken by the head of the world's nuclear watchdog.
The UAE has attributed the strike to pro-Iran Iraqi militias, a claim that sits within a much larger pattern of escalation. Since late February, when Israel and the United States launched a bombing campaign against Iran, the region has been absorbing sustained barrages of missiles and drones. The Emiratis alone have been hit by more than 2,800 such weapons. Iran has been retaliating against its neighbors, and the militias operating in Iraq appear to be part of that response network. The attack on Barakah fits into this cycle of tit-for-tat strikes, but with a crucial difference: nuclear facilities are not ordinary targets.
Grossi has convened an emergency session of the IAEA's Board of Governors to address the incident. He has also been traveling through the Gulf—visiting Kuwait and Qatar, heading next to Saudi Arabia—to assess the broader security picture. What he is hearing from regional leaders is anxiety. Several countries in the area have serious concerns about what could happen next.
The worst-case scenario, as Grossi framed it, would be a direct hit on Barakah itself, or on Iran's Bushehr nuclear plant, which has also come under attack during the conflict. Either strike could breach containment and release radioactive material across borders. The consequences would not be confined to one nation. A major nuclear accident in the Gulf would affect millions of people across multiple countries, potentially displacing entire populations and rendering large areas uninhabitable for years.
What makes the May 17th attack significant is not just that it happened, but that it succeeded in reaching its target and that the people behind it clearly understood the stakes. They were not firing blindly into the night. They were aiming at the nerve center of a nuclear facility, betting that they could trigger a cascade of failures. The fact that they came close enough for the IAEA director to call it "extremely grave" suggests that the margin between a contained incident and a catastrophe is narrower than many people realize. As the conflict in the Middle East continues to simmer and flare, that margin may only get thinner.

La Conversación del Hearth Otra perspectiva de la historia
Why does the IAEA director use the phrase "extremely grave" twice in the same statement? Is he just emphasizing, or is there something specific he's warning about?
He's signaling that the attackers were not amateurs. They targeted the electrical systems specifically—the infrastructure that keeps external power flowing to the reactor. If that fails, the reactor shuts down. If it shuts down without proper cooling, you have a problem. He's saying they knew this. They understood the vulnerability.
So this wasn't a lucky hit. This was reconnaissance.
Exactly. Someone studied the plant, identified the critical point, and sent drones to hit it. That level of sophistication and knowledge is what makes Grossi's language so stark. It's not "we were attacked." It's "we were deliberately targeted by people who understood what they were doing."
The UAE says it was pro-Iran Iraqi militias. But does that mean Iran ordered it, or just that these groups are acting in Iran's interest?
The source doesn't say Iran ordered it directly. But the timing and the pattern are clear—Iran retaliates when it's hit by the U.S. or Israel, and these militias are part of that retaliation network. Whether it's a direct order or a general alignment of interests, the effect is the same: a nuclear facility was deliberately targeted during an active conflict.
How many people could be affected if something actually goes wrong?
That's the question Grossi is asking by traveling to every capital in the Gulf. A major breach at Barakah or Bushehr wouldn't stay within borders. You're talking about radioactive contamination spreading across the region, potentially affecting millions. Displacement, long-term health effects, entire areas becoming uninhabitable. It's not a localized disaster.
Is there any indication this will happen again?
The region has absorbed over 2,800 missiles and drones since February. The conflict is ongoing. Grossi is convening emergency sessions and visiting countries because he's worried about exactly that—that the next attack might not miss, or might hit harder. The margin between what happened on May 17th and a true catastrophe is very thin.
