The International Atomic Energy Agency is pressing Iran for access to one of its most sensitive nuclear sites, as the U.N. watchdog seeks to verify whether Tehran has disclosed the full scope of its atomic program. The demand comes amid a wider standoff that saw Iran's Revolutionary Guards report explosions on two oil tankers in the Strait of Hormuz on Saturday.

The IAEA has sought to inspect the site to confirm that Iran's declared nuclear material and activities match its safeguards obligations. Iran has restricted access beyond its declared locations, and the agency has said that without physical access it cannot verify whether undeclared material or equipment is present. The agency's board has repeatedly called on Tehran to cooperate fully.

The Strait of Hormuz, where the tankers struck mines, carries roughly a fifth of global oil consumption and is the world's most important oil chokepoint. Any disruption there affects crude prices and shipping insurance worldwide. The Revolutionary Guards said the blasts occurred after the vessels hit mines, without identifying the tankers or their cargo.

The IAEA's push for access is part of a broader effort by the agency to keep tabs on Iran's nuclear program after the collapse of the 2015 Joint Plan of Action. Since the U.S. withdrew from the deal in 2018, Iran has enriched uranium to higher levels and limited monitoring of its facilities. The agency has said it cannot provide assurance that Iran's program is entirely peaceful without full cooperation.

The U.N. also called for an end to attacks on civilians in Yemen, where a Saudi-led coalition has been fighting Houthi rebels since 2015. The conflict has killed more than 150,000 people, according to the U.N., and created one of the world's worst humanitarian crises.

The IAEA's request for site access remains unresolved. Iran has not publicly agreed to the inspection, and the agency has not set a deadline for compliance. Without access, the international community has no independent means to confirm the status of Iran's nuclear material at the site in question.
