Iran Cuts Off Direct Diplomacy With U.S. - WSJ

Iran has cut off direct diplomatic ties with the United States, a move that follows the US decision to remove the country from its list of state sponsors of terrorism. The move comes after Iran's Supreme Leader Ayatollah Ali Khamenei declared that the US was 'not a trustworthy' partner. The US had been in talks with Iran over a prisoner swap and the return of billions of dollars in frozen assets. The development is seen as a significant escalation of tensions between the two countries.
