Craters can be seen at the Fordo facility, Iran's main facility for enrichment to 60 percent, says Grossi about the effects of the US bombing.
60 percent is far above what is required for nuclear power, but not all the way up to the level in atomic bombs.
In this situation, no one, not even the IAEA, is able to fully assess the damage to Fordo, Grossi means, but continues:
Given the heavy weapons used and the extremely vibration-sensitive centrifuges, very significant damage is expected to have occurred.
Like many world leaders, he urges a return to diplomacy, which is also required for more in-depth assessments to be made.
We must let the IAEA's inspectors return to Iran's nuclear facilities to check Iran's stockpile of uranium, and most importantly the 400 kilos that are enriched to 60 percent.
