Tensions in West Asia take a sharp turn as Iran abruptly walks out of high-stakes negotiations with the United States, citing a “lack of sincerity” from Washington. The diplomatic fallout comes just as hopes were building around a potential breakthrough in Islamabad-mediated talks. Tehran has directly linked its withdrawal to the reported seizure of an Iranian-flagged vessel by the US Navy in the Strait of Hormuz, one of the world’s most strategically critical oil routes. Calling the move an act of aggression, Iranian officials argue it violates diplomatic norms and undermines already fragile ceasefire commitments. Iranian Foreign Ministry spokesperson Esmail Baqai confirmed that Tehran has no immediate plans to return to the negotiating table, signaling a significant shift in posture. WATCH
