Trump's 'big decision' on Iran

Donald Trump says his officials have had a long meeting with senior Iranians on the sidelines of the United Nations General Assembly, while in his speech the US president threatened Iran with "annihilation". Also in the programme: Mahmoud Khalil, the Syrian-Palestinian graduate student detained by ICE agents at Columbia University for leading pro-Palestinian protests on campus, speaks to Newshour; and a 6-year-old Chinese girl has broken the women's world record for solving a Rubik's cube - does the skill come from innate genius or practice?
