A state of emergency and a week-long curfew has been imposed on the US city of Baltimore following a night of violent protests.
The demonstrations led to 15 police officers being injured and follow the death of a black man fatally injured in police custody.
The US justice department is investigating where and when his spinal injuries were sustained.
Officials have suspended six police officers who were involved in the case.
Monday’s clashes, which led to looting and fires in various parts of the city, began hours after the funeral of 25-year-old Freddie Gray.
The Foreign and Commonwealth Office, updating its travel advice, said: “A state of emergency was declared in the city of Baltimore following violent protests and looting.
“A curfew is in place between 10pm and 5am. You should monitor local media, avoid all protests and follow the advice of the local authorities.”
