In retaliation to the 13th November attacks in Paris, France has stepped up its bombing campaign of IS-held territory. Since the middle of last year planes from the US-led coalition have been targeting IS in both Syria and Iraq. But many people have questioned the impact of aerial bombardment. This week's audiographic gives a sense of the intensity of the bombing campaign against IS, plotting the frequency of sortie figures as sound. Photo: European Photopress Agency
