The protests, which began in Minneapolis following Floyd's death Monday after a police officer pressed a knee on his neck for more than eight minutes, have left parts of the city a grid of broken windows, burned-out buildings and ransacked stores.

The unrest has since become a national phenomenon as protesters decry years of deaths at police hands. In pic, Marcus Lavon of Des Moines raises his hands during a protest in Des Moines. (Photo: AP)

The large crowds involved, with many people not wearing masks or social distancing, raised concerns among health experts about the potential for helping spread the coronavirus pandemic at a time when overall deaths are on the decline nationwide and much of the country is in the process of reopening society and the economy.

After a tumultuous Friday night, racially diverse crowds took to the streets again for mostly peaceful demonstrations in dozens of cities from coast to coast.

The previous day's protests also started calmly, but many descended into violence later in the day.
