Multiple reports describe a developing situation involving US strikes on Tehran and ongoing US-Iran negotiations. One outlet says Donald Trump launches new strikes during a period in which negotiators are engaged in talks aimed at ending the broader conflict. In parallel, Iran claims it has shot down a US F-35 fighter jet. The available material does not provide independent verification of the claim or details on the circumstances of any alleged aircraft loss. The reports frame the events as part of escalating actions while diplomatic efforts continue, but they do not consistently specify the targets, the timing of the strikes relative to the negotiations, or the evidentiary basis for the shoot-down claim. Overall, the picture presented is that military actions occur while talks are underway, and Iran publicly asserts a successful defense against a US aircraft. Further confirmation from additional sources would be needed to corroborate the specific allegation regarding the F-35.
