A picture taken on March 3, 2016, shows the Mosul Dam on the Tigris River, around 50 kilometres north of the Iraqi city of Mosul. The US embassy in Iraq has released on February 29, 2016, evacuation recommendations it said could help save up to 1.5 million lives at risk from a catastrophic failure of the Mosul Dam. Concern has grown in recent months over a possible collapse of Iraq's largest dam, which would unleash a wave that would devastate second city Mosul and flood much of the capital Baghdad. / AFP / SAFIN HAMED
