Mass protests across Iran: but how will the authorities respond? We hear from the BBC Persian Service, where journalists are trying to monitor events amid an information blackout, and discuss Supreme Leader Ali Khamenei's options with Iranian-American journalist Hooman Majd.

Also in the programme: Colombian President Gustavo Petro's views on United States policy in Latin America; and Elon Musk's former partner Ashley St Clair explains her concerns about sexualised images made by the Grok AI chatbot on X, formerly known as Twitter.
