Iranian supreme leader Ayatollah Ali Khamanei says Iran is prepared to increase its uranium enrichment to sixty per cent amid Western pressure to re-enter the 2015 nuclear deal. If Iran follows through on the ayatollah’s threat, it would be tripling the purity of its current uranium stockpile and exceeding the limits laid out in the 2015 deal by sixteen-fold. The United States and several European nations are pressuring Iran to return to the nuclear deal after former US President Donald Trump pulled out in 2018.
