The death of George Floyd -- a 46-year-old Black man -- on May 25 in Minneapolis, United States as he was being detained by four police officers sparked fury across the United States, but has also proven to be the catalyst for anti-racism movements around the world. The killing has spurred millions of people into taking action, with protesters filling the streets and taking to social media. Agora, a photography app company that compiles photographs submitted by its users -- both amateur and professional -- and that runs photography awards to showcase the best submissions has released a series of images taken during the Black Lives Matter movement as part of the company's own #StopRacism campaign.
