Iran's foreign minister is planning a call with French, German, and British counterparts to avoid U.N. sanctions over its nuclear program. The call planned for Friday, reported by Iran's state-run IRNA news agency, comes as these countries threaten to reimpose sanctions using a "snapback" mechanism from the 2015 nuclear deal. Concerns have grown since Iran cut off cooperation with the International Atomic Energy Agency after a conflict in June. The European deadline is August 31. Restoring IAEA access is crucial, but Iran has complicated talks by threatening the IAEA's director-general. The "snapback" power expires in October, adding pressure.
