The activist computer hacker group Anonymous is calling for protests and cyber attacks during a "day of solidarity" with the Black Lives Matter movement around the country this week.

"Anonymous has declared a day of action in solidarity with the Black Lives Matter movement and the victims of Police Brutality as well as alongside the families of Alton Sterling and Philando Castile," the statement says, which appears under a video on YouTube. 

The statement links to a list of protests allegedly planned at 37 cities around the country on Friday, Newsmax reports.
