Bystanders look on as floodwaters rage past a damaged building in an area of Freetown on August 14, 2017, after landslides struck the capital of the west African state of Sierra Leone.               
At least 312 people were killed and more than 2,000 left homeless when heavy flooding hit Sierra Leone's capital of Freetown, leaving morgues overflowing and residents desperately searching for loved ones. An AFP journalist at the scene saw bodies being carried away and houses submerged in two areas of the city, where roads turned into churning rivers of mud and corpses were washed up on the streets.
