YESTERDAY: PROTESTS against two fatal police shootings have continued across America in the wake of a Dallas protest that turned deadly.
Video that surfaced on social media showed officers used tear gas and rubber bullets at a rally in Phoenix on Saturday (Australian time) when protesters threw rocks at the line of police dressed in riot gear.
Marchers chanted "hands up, don't shoot," as they walked through the city and attempted to walk on a highway still in use by traffic.
The Phoenix police service said via Twitter that a person suspected of throwing rocks was in taken into custody.
Local media reported the protest was then shut down, after helicopters and armoured vehicles had been deployed.
Earlier in the day rappers Snoop Dogg and The Game met with police executives in Los Angeles after organising a peaceful march to police headquarters.
"There's no way this can keep going on," Snoop said in a video posted to his Twitter account.
"They (the police and mayor) gave us their attention, their undivided attention."
"They heard us speak and we'll come back and dialogue some more and put some plays together.
Other rallies and vigils were also held in Detroit, New York, Washington and other cities.
In Dallas, a city in mourning after the deaths of five police officers at a protest yesterday, people gathered in memorial rather than in protest.
An alleged lone sniper targeted white police officers at a protest yesterday. Police officers used a bomb robot to kill the sniper and end a siege in a Dallas parking garage.
The rallies were prompted by the shootings of Philando Castile in Minnesota and Alton Sterling in Baton Rouge.
The aftermath of Mr Castile's shooting was live streamed on Facebook when his partner, Diamond Reynolds, began to film the officers who shot her boyfriend during a traffic stop.
He was shot after he told officers he had a gun, which he was legally allowed to carry, in the vehicle.
The graphic video shows Ms Reynolds being arrested after officers shot Mr Castile.
It has been watched more than four million times.
