VIENNA: Iran has started the process of enriching uranium to 60 per cent fissile purity at an above-ground nuclear plant at Natanz, the UN nuclear watchdog said yesterday.
The move has complicated talks aimed at reviving Iran’s nuclear deal with major powers as it is a big step towards producing weapons-grade uranium.
Iran had previously only reached 20pc purity, and that was already a breach of the deal, which says Iran can only enrich to 3.67pc.
