Iran’s Supreme Leader Ayatollah Mojtaba Khamenei has ordered that the country’s stockpile of highly enriched uranium must not be sent abroad under any circumstances. The directive directly contradicts a key demand from the United States, which had made the removal of enriched uranium a central condition in ongoing peace discussions. Two senior Iranian sources confirmed the order to Reuters.

According to the report, the decision could anger U.S. President Donald Trump and place the process of ending the ongoing conflict with the United States and Israel in serious doubt. Israeli officials told Reuters that Trump had previously assured Israel that Iran’s uranium stockpile would be removed and that this would be a mandatory clause in any peace agreement. Israel’s Prime Minister Benjamin Netanyahu has also stated that the war would not be considered over until Iran removes its enriched uranium, halts support for proxy militias, and dismantles its ballistic missile capabilities.

Iranian officials believe that sending the material abroad would leave the country more vulnerable to potential attacks from the United States and Israel. No immediate comment was available from the White House or Iran’s Foreign Ministry.
