The police killing of George Floyd, an unarmed Black man, in Minneapolis, Minnesota, on May 25 sparked protests across the United States and worldwide.
A video of the incident shows Derek Chauvin, a white police officer, kneeling on Floyd's neck for nearly nine minutes as the 46-year-old pleaded: "I can't breathe."
Following the killing, protests erupted in at least 140 US cities, with thousands of people taking to the streets against police violence. While protests have remained largely peaceful, looting, vandalism and fires have taken place in some cities. The police have also used tear gas and other non-lethal projectiles on protesters, including on peaceful gatherings.
National Guard troops were activiated in more than 20 states, and several cities imposed temporary curfews.

In Minneapolis, separate autopsy reports released by independent and county medical examiners agreed in ruling Floyd's death was a homicide, but they differed in part on the cause.

The Hennepin County Medical Examiner found that Floyd "experienced a cardiopulmonary arrest while being restrained by law enforcement officer(s)". It said Floyd suffered "other significant conditions", including heart disease and hypertension, fentanyl intoxication and recent methamphetamine use.

"Teach them what necessary force is," he says. "Teach them that necessary force should be used rarely, and only when life is at risk."
He also reminds the panel that police were called because his brother had allegedly used a counterfeit $20 bill.

Army General Mark Milley, the US's highest-ranking military officer, said he was wrong to have accompanied Trump on a walk to a church outside the White House, where he was photographed in his combat uniform with the presidential entourage.
"My presence in that moment and in that environment created a perception of the military involved in domestic politics," Milley said. "As a commissioned uniformed officer, it was a mistake that I have learned from, and I sincerely hope we all can learn from it."
Trump meanwhile attacks leaders in Washington state over actions taken by protesters there. Protesters and self-described anarchists have created what they are calling a "Capitol Hill Autonomous Zone", occupying several city blocks after police vacated a precinct there.
Trump on Twitter demands Seattle's mayor and Washington's governor to "take back" the city. Mayor Jenny Durkan shoots back, tweeting: "Make us all safe. Go back to your bunker."
