Fifteen police officers have been injured in violent protests on the streets of Baltimore in the US.

The force says some have broken bones after they were hit with bricks and rocks.

The trouble started after the funeral of Freddie Gray - a black man who died after he sustained a spinal injury in police custody.

A week-long curfew is in place in the city, and the US National Guard has been called in.

Larry Hogan's the Governor of Maryland.
