Iran said Monday it will consider withdrawing from the Treaty on the Non-Proliferation of Nuclear Weapons (NPT) if a dispute over its atomic programme goes before the UN Security Council. Britain, France and Germany launched a process last week charging Iran with failing to observe the terms of the 2015 nuclear deal, a move that could eventually see the Security Council reimpose international sanctions on the country. Iran has accused the three EU member states of inaction over sanctions the United States reimposed on it after unilaterally withdrawing from the landmark accord in 2018.
