Iran remains 'obsessed' with building nuclear deterrent despite damage incurred from U.S. strikes last month, but suggests its still open to negotiation in a move that one expert warns is a ploy to buy time.

Though the ceasefire between Israel and Iran has been holding, 'The war remains an unfinished project, for both sides,' one Middle East expert warns.

Iran also criticized the IAEA, and Grossi directly, for not condemning the U.S. and Israel for attacking its nuclear facilities, which Iran considered a violation of international law. In May, the IAEA censured Iran, claiming the country had stockpiled enriched uranium to near weapons-grade levels of 90%.
