Iran's Foreign Minister Abbas Araghchi is set to hold a conference call with his French, German, and British counterparts to prevent the reimposition of UN sanctions related to Tehran's nuclear program, just before the deadline. The call comes amid growing concerns over Iran's uranium enrichment activities and its lack of cooperation with the IAEA. The European nations have warned Iran of 'snapback' sanctions if a satisfactory solution is not reached by August 31. The situation is complicated by Iran's threats against the IAEA's director general and the expiration of 'snapback' powers in October.
