WASHINGTON-: The United States and Iran have offered sharply different interpretations of key provisions in a framework agreement designed to end months of conflict, exposing deep divisions over nuclear inspections, access to frozen assets and regional security arrangements despite a tentative ceasefire. The disagreements emerged just days after negotiators from both countries concluded an initial round of talks in Switzerland, raising fresh doubts about the durability of a deal intended to bring an end to the war that erupted earlier this year. US President Donald Trump maintained that discussions with Tehran were progressing positively and told supporters at a rally in Pennsylvania that relations between the two sides had improved. However, Iranian officials rejected several of Washington’s claims regarding the content of the negotiations, suggesting that major issues remain unresolved.
