Hundreds of protesters in Philadelphia have marched through the city for a second night, demanding racial justice after police fatally shot a black man, writes BBC.

The family of Walter Wallace, 27, say he was suffering a mental health crisis when officers opened fire on him.

Police say they shot him because he wouldn’t drop a knife he was holding.
Police reinforcements as well as the National Guard have been deployed. Officials say 30 officers were hurt during the first night of clashes.
