Hours earlier, the chief of Iran’s civilian nuclear program insisted his country would refuse the agency access to a sensitive centrifuge assembly plant. Tehran has offered no evidence to support the claim, though it’s another sign of the friction between inspectors and Iran. “There’s no other country other than those making nuclear weapons reaching those high levels” of uranium enrichment, Grossi said of Iran. Grossi said Iran has informed the IAEA about the ongoing construction and his inspectors “are following” progress at the sites. Iran often points to Israel’s weapons program as an international double-standard given the scrutiny of Tehran’s civilian program.
