Syria’s notorious Saydnaya prison is one of many that have been liberated as rebels take control of the country. We hear from our correspondent Barbara Plett Usher who has been inside the prison where thousands of opposition supporters are said to have been tortured and executed under the Assad regime. Family members rushed in to see if their relatives were among those released. But will these people find answers in their search? And what will this mean for Syria’s future?

On this episode Azadeh Moshiri is joined by the BBC’s Middle East regional editor Sebastian Usher who compares the collapse of the regime to the start of the civil war, which began in 2011.
