Rioting in Baltimore over death of Freddie Gray

Police say at least seven officers have been injured in a violent clash with a large group of youths.

One officer is described as unresponsive, while others have broken bones after people threw bricks, rocks and other items at police.

Television images show a drug store being looted and police in riot gear forming a line nearby.

The riot started just hours after a funeral for Freddie Gray, who died of a mysterious spinal injury while he was in police custody.
