Tehran warns of serious ramifications in the case of a US military strike, after a US aircraft carrier arrives in the Middle East. President Trump says he believes the regime still wants talks, so what is about to happen? We talk to an influential Iranian activist who has survived multiple attempts on her life (she will face her alleged Iranian state-backed assassin in a New York court tomorrow) and an Iranian protester who saw people killed by the authorities right in front of her. With Victoria Derbyshire.
