Iran has ramped up its uranium enrichment again, and the UN’s nuclear watchdog is sounding the alarm.
In a confidential report seen by the BBC, the International Atomic Energy Agency (IAEA) revealed that Tehran now holds over 400kg of uranium.
It is enriched to 60% purity.
That’s dangerously close to weapons-grade—and nearly a 50% jump in just three months.
To put that in perspective: if further refined, it’s enough material for around 10 nuclear bombs.
And no other non-nuclear-armed country is producing uranium at this level.
Iran insists its nuclear programme is for peaceful purposes.
But the IAEA’s Director General Rafael Grossi isn’t convinced.
“The significantly increased production and accumulation… is of serious concern,” he said.
What’s More Concerning?
Iran’s current pace means it could be producing enough material for one bomb every month.
The report could trigger a formal rebuke from the US, UK, France, and Germany at the IAEA’s board of governors.

Meanwhile, Israel claims Iran is “totally determined” to build nuclear weapons—calling the enrichment levels “indefensible.”
Iran’s top negotiator, Abbas Araghchi, fired back: “We agree. Nuclear weapons are unacceptable.”
So if no one wants nukes… why is everyone acting like they’re building one?
