Members of Ocean Rebellion, an art collective formed out of Extinction Rebellion, protest outside the London headquarters of the UN's International Maritime Organization (IMO) against what they describe in a press release as a "failure... to tackle shipping emissions". The IMO, which oversees the highly polluting shipping industry, made a landmark deal on Friday to cut emissions, but campaigners say it falls short. "The IMO voted to do little or nothing" says Clive Russell, one of those protesting in London. IMAGES AND SOUNDBITES
