The US Secretary of State, Anthony Blinken, has warned that every precaution must be taken to avoid harming civilians, as Israel prepares a major ground offensive in Gaza. Also in the programme: we hear from the Jordanian foreign minister; a senior member of Hamas; and the Israeli ambassador to the UK. We also speak to an IDF reservist in New York who explains why he will be fighting in this war. (Picture: Residents of Gaza City continue to evacuate.
