Iran’s Supreme Leader says US breaches show Trump’s signature is ’worthless’

Reuters - Iran's Supreme Leader Mojtaba Khamenei said ​in a written statement ‌on Saturday that repeated U.S. breaches of a ​memorandum of understanding ​signed by the presidents ⁠of Iran and the ​United States had ​shown that President Donald Trump's signature was "utterly worthless and devoid ​of credibility."
Washington and ​Tehran have exchanged strikes after ‌a ⁠ceasefire agreement fell apart last week, raising fears of a return ​to ​all-out ⁠war.
Khamenei said the United States should ​know that the ​Iranian ⁠nation and the "resistance front" had "unforgettable lessons" for ⁠it.
