A black man has been shot dead by police in the US state of Minnesota as protests continued over the police killing of a black man in Louisiana.
Philando Castile was shot in his car as he reached for his driving licence, his girlfriend said in a Facebook Live video taken during the aftermath.
It follows the death of Alton Sterling, who was shot dead by police during an incident in Baton Rouge on Tuesday.
Hundreds of people have protested for two nights over Mr Sterling's killing.
The deaths follows a long line of high-profile incidents involving African-Americans at the hands of the police, igniting a national debate about the lethal use of force.
