US President Donald Trump criticises Iran after Tehran denies participating in peace talks, with Trump saying Iran is “unbelievably duplicitous.” The dispute follows Trump’s statement that Iran called off what he described as “the biggest attack since World War II.” According to the outlet, Trump’s remarks frame Iran’s denial as inconsistent with the US account of events leading to the breakdown in talks. The reporting focuses on Trump’s language and the immediate diplomatic blame attributed to Iran, rather than presenting detailed evidence or additional documentation of the claims. The outlets do not describe specific negotiation details, dates, or participants, nor do they provide an Iranian response beyond the denial referenced by the US president. The present reporting therefore centres on the US accusation and its connection to the cessation or collapse of attempted talks, alongside Trump’s broader characterization of the alleged incident as unprecedented in scale. The story remains focused on competing assertions about whether peace discussions occurred or were cancelled.
