Iran is 'dramatically' increasing its uranium enrichment to near bomb-grade levels, according to the International Atomic Energy Agency (IAEA) chief. The move is causing alarm in Western capitals, as no other country has enriched uranium to this level without producing nuclear bombs. Iran already has enough material enriched to 60% purity for four nuclear weapons, and its production capacity is set to increase further. This escalation comes after unsuccessful talks between European and Iranian officials, and as the Trump administration staffs up with noted hawks on Iran. The IAEA chief expressed regret that there is currently no diplomatic process to de-escalate tensions with Iran.
