Fresh tensions have emerged between Washington and Tehran after Iran accused the U.S. of attempting to reinterpret key provisions of the June 17 peace framework. The dispute was triggered by comments from Secretary of State Marco Rubio questioning whether regional hostilities can fully end while Iran-backed groups remain active. Iranian officials insist that a complete ceasefire across the region is a core pillar of the agreement and warn that any effort to alter its terms could undermine trust and complicate implementation.
