Hundreds of demonstrators marched across the six-city Hampton Roads, Virginia, area as part of a coordinated effort to speak out against violence by police against blacks.

Blacklivesmatter757 organized the protests in response to the shootings of black men in Baton Rouge, Louisiana, and Falcon Heights, Minnesota. The organization called for protesters to shutdown streets in Hampton, Norfolk, Newport News, Chesapeake and Portsmouth and the waterfront in Virginia Beach on Sunday evening.

Video from the scene in Newport News shows protesters on a street corner holding signs and chanting "no justice, no peace" and "black lives matter." Some marchers spilled into the street blocking traffic as police cars stood by.
