The Rohingya refugee crisis is an age-old tale of displacement and suffering, but technology is providing new tools to tackle it, rights groups and charities said on Wednesday. Powerful drone and satellite images are bringing to life the urgent needs of more than 800,000 Rohingya refugees who fled to Bangladesh from Myanmar, while also providing strong evidence of abuses, which could be used to lobby for justice. The UNHCR is using videos and photographs shot with drones to show the scale of the displacement crisis and bring it to life to spur action from the public and donors.
