Iran accelerates enrichment of uranium to 60 per cent fissile purity

Iran has accelerated its enrichment of uranium to near weapons grade, UN atomic watchdog said

The move has increased tension with the West as both sides seek to resume talks on reviving the 2015 nuclear deal between Iran and global powers.

Iran is refining uranium to 60 per cent fissile purity from 20 per cent in April, in response to an explosion and power cut at its Natanz site, which damaged production at the main underground enrichment plant.

Uranium metal can be used to make the core of a nuclear bomb but Iran says its aims are peaceful and it is developing reactor fuel.
