U.S. President Donald Trump says he rejects Iran’s latest response to a U.S. ceasefire proposal, according to reporting from multiple outlets. Iran sends its reply through Pakistani mediators, with Iranian state media reporting that the message is delivered to Pakistan for transmission to Washington. The outlets describe that Iran’s response is submitted to Pakistani intermediaries on Sunday. Details of the content of Iran’s message are not disclosed in the available reports. NPR reports that Iran delivers its response to Pakistani mediators as part of the exchange connected to the U.S. ceasefire proposal. Mint similarly reports that Iranian state media has already announced Tehran’s submission of the response via Pakistani channels, while providing no specifics about what the response contains. Mint also reports Trump’s characterization of the response, describing it as “totally unacceptable.” Both accounts frame the development as part of ongoing diplomatic efforts tied to the U.S.-Iran ceasefire proposal and a continued back-and-forth in which neither the full terms of Iran’s reply nor any additional response from Washington is detailed beyond Trump’s public rejection.
