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.
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 follow a long line of high-profile incidents involving African-Americans at the hands of the police, igniting a national debate about the use of lethal force.
As news of the latest shooting spread, about 200 people protested outside the St Paul home of Minnesota Governor Mark Dayton, who later requested a federal investigation into the shooting.
He said he had been in contact with the office of President Barack Obama who was "shocked and concerned" at the situation. Black US tennis player Serena Williams, who is playing at the Wimbledon tournament, also expressed her dismay at news of Mr Castile's death, tweeting:
"In London I have to wake up to this. He was black. Shot 4 times? When will something be done - no REALLY be done?!

Before he was shot, he told the officer that he was licensed to carry a concealed gun and had one in his possession, she said.
"You shot four bullets into him, sir. He was just getting his licence and registration, sir," Ms Reynolds says in the video.
