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.

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.

Israel carried out it first strikes against Houthi targets in Yemen since the Israel-Iran ceasefire, attacking ports and a power plant around midnight local time Sunday night into Monday morning.
