UN inspectors to visit Iran nuclear sites under US-Iran agreement

UN inspectors are scheduled to visit Iran nuclear sites under a US-Iran agreement to potentially stabilize regional tensions and secure a comprehensive nuclear deal. However, the UN nuclear boss and Tehran disagree on the timing, with Iran insisting on a final deal first. Meanwhile, reports indicate Iran has denied IAEA access to these sites, which complicates ongoing US deal talks and increases the risk of regional instability as both nations dispute the interim document's meaning.
