Ferguson police shooting 'an ambush', says Eric Holder
US Attorney General Eric Holder has described the shooting of two police officers in the racially-charged city of Ferguson in Missouri as ''a disgusting and cowardly attack''.
Two officers were seriously injured during protests following the resignation of the police chief after a damning report about racial bias.
The fatal shooting of a black teenager last year in Ferguson sparked protests about the police use of lethal force.
