Dallas, August 1 (RHC)-- Hundreds of U.S. demonstrators have marched through Dallas, Texas, to express their anger against police brutality toward African-Americans. The protesters also paid homage to the five police officers slain by a sniper during a demonstration in Dallas last month.

The protesters marched several blocks from a downtown park to El Centro College, where a gunman identified by police a Micah Johnson fatally shot five police officers on July 7.

The march was organized by a civil rights group called the Next Generation Action Network, the same civil rights group that held the July 7 protest which ended with gunfire. The protesters chanted slogans and condemned police violence against the Black community.

Dallas police helicopters circled overhead during the weekend march, and officers armed with rifles in riot gear ordered protesters off the streets to the sidewalks. The move has drawn widespread condemnations prompting U.S. authorities to step up security measures to protect law enforcement officers nationwide.

Over the past month, thousands of demonstrators have flooded the streets of major cities across the country to decry the deaths of Alton Sterling and Philando Castile, two Black men who were killed by police just one day apart.
