Turkish authorities have detained Ekrem Imamoglu, from the secular opposition Republican People's Party (CHP), just days before he was due to be selected as a presidential candidate. Also on the programme, the United Nations says one of its international staff has been killed when an explosive was dropped on or fired at a UN compound in central Gaza; and a conversation with Hans Zimmer about his 40 years composing some of the most memorable film music.
