Black Lives Matter protesters argue with a man who claimed to be a U.S. army veteran during unrest in Rochester, New York, on Sunday night (September 13).

The BLM group clashed with the man, exchanging strong language and rival chants of 'All Lives Matter' and 'Black Lives Matter'. He then walked away past the entrance of City Hall.

Rochester has been the focus of race demonstrations in recent weeks after the death of Daniel Prude, 41, earlier this year.

The black citizen was found running naked in the street in light snowfall in Rochester. He restrained him with a "spit hood", which is designed to protect police from detainees' saliva.

Prude died a week later but footage of the incident only emerged last week, sparking riots similar to those seen in Minneapolis, Minnesota over the death of George Floyd and in Kenosha, Wisconsin, in relation to the police shooting of Jacob Blake.
