What is happening now in Syria “is paving the way” for the Islamic State group to re-emerge. That’s according to a leading Kurdish commander who played a key role in defeating the group in Syria in 2019. General Mazloum Abdi told the BBC that IS activity has “increased significantly” and the danger of a resurgence has doubled. Our senior international correspondent Orla Guerin was given rare access to the largest IS jail - in the city of Al Hasakah.

Also in the programme: A BBC investigation has found that the embattled military rulers of Myanmar control less than a quarter of the country; Malaysia has authorised a new attempt to find the wreckage of MH-370 - the flight that disappeared ten years ago; and the group of singers, with an average age of 92, which has broken the Guinness World Record for the world's oldest choir.
