On Tuesday, Iran's deputy foreign minister and a top nuclear negotiator Abbas Araghchi told state-run Press TV that the International Atomic Energy Organization (IAEA) had been informed of Tehran's decision to ramp up enrichment to 60 percent purity, a big step up from the current 20 percent purity levels.
