Hurricane Harvey has dumped record amounts of rain onto the Texas city of Houston, leaving at least eight dead and thousands stranded and prompting an unprecedented rescue effort.
As a result of the rains, swollen bayous and releases of water from reservoirs, large swaths of the fourth-largest city in the US is under water.
