US protestors

Protesters march again in US cities: 'Silence is violence'

The throng at the capitol then stood up and chanted "take a knee" and "who do you protect?" as officers faced them.

Evening curfews were ordered in dozens of cities following a week of protests over the death of 46-year-old George Floyd in Minneapolis police custody.

Largely peaceful during the day, crowds have in previous nights erupted into vandalism, arson and looting after dark.
