Reuters said: "The shooting was the second high-profile killing of a black man by police in Minnesota in seven months".
Kelly said Yanez, who is Latino, is "overcome with sadness" over Castile's shooting Wednesday in the St. Paul suburb of Falcon Heights, a mostly white community of 5,000 that is served primarily by the nearby St. Anthony Police Department.
Tyree Johnson, who said he was Castile's cousin, said officers on the highway fired pellets and gas in his direction.
Choi declined to provide details about the incident.
But while this audio may document that a police officer thought Castile might have resembled a person wanted for armed robbery, that didn't mean he was a "suspect" in an armed robbery case or that he was "wanted" for armed robbery - at the time he was killed, nothing linked him to such a crime other than that an officer momentarily thought Castile might have looked a little like someone who had committed a robbery.
Ban also condemned the killing of five police officers in Dallas, his spokesman Farhan Haq said in a statement.
"Like a lot of you guys, I watched the videos, and was appalled and completely heartbroken".
"We must do better in our state and in our nation to improve police-community interactions to ensure the safety of everyone in this country, but particularly the safety of African-Americans, who disproportionately lose their lives as a result", Choi said during a news conference Friday. On Thursday, Minnesota Governor Mark Dayton said that he believed Castile would still be alive if he and the other passengers in the vehicle had been white. "I don't think it would have", Dayton told reporters.
On Thursday night, a gunman ambushed police officers who had been protecting a downtown Dallas protest responding to the deaths of Castile and Alton Sterling, the black man recently killed by police in Louisiana.
Authorities say the lone sniper in the Dallas attack was killed early Friday when an explosive on a remote-controlled police robot was detonated.
In the span of four days, the United States has had to come to terms with the deaths of two black men at the hands of police - the first caught on video and the aftermath of the second livestreamed on Facebook - as well as the deadliest day for USA law enforcement since 9/11. That incident was also caught on video.
Choi said his office has not yet met with Castile's family, saying it wouldn't be appropriate until investigators completed their work.

Richmond went on to say that Castile had done the right things by having a license to carry a concealed weapon, and by telling the officer that shot him he was carrying a gun. "As he was putting his hands back up, the officer shot him in the arm four or five times".
Police Officer Jeronimo Yanez shot Philando Castile, 32, in the driver's seat of a auto on Wednesday night in the Falcon Heights neighborhood, just outside the state capitol. Both were put on administrative leave, as is standard.
At some point during the interaction, Yanez shot Castile multiple times.
Several videos, including squad auto video, have been collected, though St. Anthony officers don't wear body cameras, authorities said.
