What to know as Iran and the US weigh holding a second round of nuclear talks

Iran and the United States are considering a second round of talks over Tehran's nuclear program. This comes after Israel launched a 12-day war on Iran in June, and Iran cracked down on nationwide protests. U.S. President Donald Trump has increased pressure on Iran, moving military assets to the Gulf and suggesting possible attacks. Trump has also pushed Iran's nuclear program back into focus after the June conflict disrupted previous talks. Iran insists it is not seeking nuclear weapons and wants talks to focus solely on its nuclear program. The situation remains tense, with concerns over a potential regional conflict.
