Another night of unrest in every corner of the country left charred and shattered landscapes in dozens of US cities on Sunday as years of festering frustrations over the mistreatment of African-Americans at the hands of police boiled over in expressions of rage met with tear gas and rubber bullets.

Cars and businesses were torched, the words "I can't breathe" were spray-painted all over buildings, a fire in a trash bin burned near the gates of the White House, and thousands marched peacefully through city streets to protest the death of George Floyd, a black man who died on Monday after a white Minneapolis officer pressed his knee on his neck until he stopped breathing.
