When the American troops withdrew from Afghanistan, they left behind $7bn of military supplies. Where are they now? Hafizullah Maroof from BBC Afghan will take us inside the Kabul flea market that sells second-hand military equipment to the Taliban. Plus: the origin story of capoeira, the Afro-Brazilian sport that blends dancing and martial arts, with Joao Fellet from BBC Brazil and Debula Kemoli from BBC Africa; and how the BBC's Pronunciation unit works with Language Service journalists to make sure we get international names right, with Martha Figueroa-Clark and Jo Kim.
