The UN nuclear chief has highlighted serious concerns regarding Iran's cooperation with international nuclear inspectors, noting that access to key nuclear facilities has been denied. This lack of transparency has raised significant worries about Iran's compliance with international nuclear regulations. The watchdog emphasized that Iran must "seriously improve" its cooperation to ensure proper monitoring and verification of its nuclear activities. The situation underscores ongoing challenges in maintaining effective oversight and upholding global non-proliferation standards. Without increased transparency and access, the international community remains uncertain about the true nature of Iran's nuclear program. These developments call for renewed diplomatic efforts to address the impasse and reinforce commitments to nuclear accountability.
