VIENNA (TIP): Iran has accelerated its enrichment of uranium to near weapons-grade, the UN atomic watchdog said in a report on august 15, a move raising tensions with the West as both sides seek to resume talks on reviving Tehran’s nuclear deal.

Iran increased the purity to which it is refining uranium to 60 per cent from 20 per cent in April in response to an explosion and power cut at its Natanz site that damaged output at the main underground enrichment plant there.

Iran has blamed the attack on Israel. Weapons-grade is around 90 per cent purity.

In May, the International Atomic Energy Agency (IAEA) reported that Iran was using one cascade, or cluster, of advanced centrifuges to enrich to up to 60 per cent at its above-ground pilot enrichment plant at Natanz. The IAEA informed member states on Tuesday that Iran was now using a second cascade for that purpose, too.  – ( Reuters)
