Iran said Tuesday that the UN's nuclear watchdog, the International Atomic Energy Agency (IAEA), will not be able to inspect key nuclear sites bombed by the US and Israel last year, as the first round of talks to end the Middle East war wrapped up in Switzerland. Tehran and Washington have signed a memorandum of understanding to end a war that sowed chaos across the Middle East and rattled the global economy, embarking on a 60-day period to settle broader issues including Iran's nuclear programme and sanctions relief.

But US President Donald Trump later said Iran had signed off on comprehensive nuclear inspections. "Iran has fully and completely agreed to highest level Nuclear inspections long into the future," he posted on social media. When the US joined Israel's war with Iran in mid-2025, it bombed nuclear facilities at Fordow, Natanz and Isfahan, including with powerful bunker-busting bombs. The extent of the damage remains unknown despite Trump claiming they were "obliterated". Iran's UN ambassador Ali Bahreini also told reporters Tuesday "there hasn't been such a decision" to accept IAEA inspectors.
