Millions of people have been affected by floods in Pakistan, hundreds have been killed, and the government has declared a national emergency. On Friday, the National Disaster Management Authority said more than 900 people had been killed since June - including 34 in the past 24 hours. In the old town of Sukkur in southern Sindh province, worn tents line the streets, as people seek shelter. Many sit with just beds - all their possessions lost to the water. The streets are flooded, and plastic waste has spewed out of sewage pipes. Large pools of dirty water have collected, slowing down any drainage. Residents are worried the standing water will bring waterborne diseases with it. It's been raining all week in Sindh province and there's been little respite for communities hoping to return home to see what can be salvaged. A number of homes in the city centre have been damaged - left with just the walls.
