War on Corruption: Indonesia’s Foreign Minister Hassan Wirayuda takes aim at corruptors with a guitar fashioned in the style of a rifle, at a United Nations anti-corruption conference in Nusa Dua, Bali, this week. The unusual musical instrument – called escopetarra and famously made by the owner from pieces of a weapon – was handed to the minister by Colombian musician and activist César López (seen bending, closing the guitar box), who performed at the meeting on Monday. Delegates from 140 countries attended the five-day event, which ended on Friday and sought ways to combat corruption around the world.
