Iran says its nuclear program is for peaceful purposes but has hardened its stance on enrichment following attacks

Rafael Mariano Grossi, director general of the International Atomic Energy Agency, told CBS that Iran had a "a very vast ambitious" nuclear program.

Pentagon reports Iran's nuclear facilities were "completely obliterated" in June strikes, offering a more optimistic assessment than earlier estimates while Iran acknowledges damage.
