DUBAI: Iran’s Supreme Leader Ayatollah Ali Khamenei has banned weapons of mass destruction, which “clearly means Tehran won’t develop nuclear weapons”, President Masoud Pezeshkian said on Thursday. Pezeshkian was speaking ahead of a third round of nuclear talks with the US, which continues to accuse Tehran of seeking nuclear weapons. Khamenei, who has the last say on Tehran’s nuclear programme, banned the development of nuclear weapons in a fatwa, or religious decree, in the early 2000s.
