Press secretary Karoline Leavitt says the US president believes there is a "substantial chance of negotiations" with Iran "in the near future".

In a post on his Truth Social platform, Trump had directly threatened the Iranian Supreme Leader, saying he knew "where the so-called ‘Supreme Leader’ is hiding."

"Iran continues to seek expansion of its influence in the Middle East, despite the degradation to its proxies and defenses during the Gaza conflict. Iran has developed and maintains ballistic missiles, cruise missiles, and UAVs, including systems capable of striking U.S. targets and allies in the region," Gabbard said.
