Thousands of troops and outside police officers have been deployed to the US city of Baltimore, following violent protests linked to the death of a black man fatally injured in police custody.
A week-long curfew has been announced. Schools and many businesses are closed.
Hundreds of people set fires, looted stores and confronted police across the city.
The rioting came after the funeral of Freddie Gray, a black man fatally injured in police custody in Baltimore.
