The US city of Houston is in the grip of the biggest storm in the history of the state of Texas, officials say, the BBC reports.
A record 30in of rain (75cm) has fallen on the city in the wake of Hurricane Harvey, turning roads into rivers.
The area is expected to have received a year’s rainfall within a week. Five people are reported dead. Helicopters have plucked victims from rooftops.
With rescue services overstretched as the rain continues, many people are having to fend for themselves.
Hospitals have been evacuated and thousands of people are without electricity.
