Thousands of people are spending the night in temporary shelters in the Chinese city of Tianjin after two massive explosions at the industrial port on Wednesday night.
At least 50 people were killed and more than 700 injured, but many are still missing, and the death toll is expected to rise.
The blasts took place in a storage area handling gas and toxic chemicals, and there are fears of widespread contamination.
From Tianjin, The BBC's John Sudworth reports.
