Iran is "pressing the gas pedal" on its enrichment of uranium to near weapons grade, U.N. nuclear watchdog chief Rafael Grossi said on Wednesday, adding that Iran's recently announced acceleration in enrichment was starting to take effect.

Iran has significantly accelerated its uranium enrichment to levels nearing weapons-grade, according to U.N. nuclear watchdog chief Rafael Grossi. This move has prompted concern from Western powers, who argue it indicates no civil justification.

Iran currently has about 200 kg of uranium enriched to up to 60% purity, close to the roughly 90% of weapons grade, U.N. nuclear watchdog chief Rafael Grossi told reporters at the World Economic Forum on Wednesday.

Grossi said a recent acceleration in enrichment to up to 60% by Iran had multiplied its production rate at that level by seven.

During the World Economic Forum in Davos, Rafael Grossi, Director General of the International Atomic Energy Agency (IAEA), revealed that Iran possesses about 200 kilograms of highly enriched uranium.

Tehran delivered a conciliatory message to Western leaders in Davos days after its arch adversary Donald Trump's return to the White House.
