Iran has offered to cap its stock of uranium just shy of weapons grade in an attempt to prevent a Western push for a resolution against it at the U.N. nuclear watchdog's board meeting. The offer is conditional on Western powers abandoning their push for a resolution against Iran. Western diplomats dismissed Iran's overture as yet another last-minute attempt to avoid censure. The aim of the resolution is to pressure Iran to return to the negotiating table to agree fresh restrictions on its nuclear activities since a 2015 deal with far-ranging curbs fell apart.
