Officials on Sunday braced for a sixth night of protests over the recent police killing of George Floyd, with additional curfews enacted and President Donald Trump urging states and local governments to call in the National Guard for additional law enforcement support.

The preparations come after tens of thousands of people on Saturday took to the streets both peacefully and violently to protest the death of Floyd, a Black Minnesota man who died in police custody on Monday, and the others who came before him.

They keep killing our people, 15-year-old Mahira Louis who marched with her mother and hundreds of other protesters through downtown Boston on Sunday told The Associated Press. Im so sick and tired of it.
