Ustta, a labourer, who has been displaced by heavy floods a year ago, works on a portion of a newly constructed house in Karampur, about 70 km (43 miles) from Sukkur, located in Pakistan's Sindh province on June 26, 2011. Up to five million people in Pakistan are at risk from floods this year, partly due to poor reconstruction and the inadequate rehabilitation of survivors who are still reeling from last year's epic deluge, the United Nations said.
