Activists on social media shared a video clip of the federal forces assaulting a young American woman at dawn Monday in Portland, Oregon, as she shouted under the soldiers' flight "I can't breathe."

The videos showed the federal forces assaulting the young woman bleeding, with soldiers sitting on her back, pressing their hands and a stick on her neck, which made her try to resist and called on them to stop, saying, "I can't breathe."

Twitter users also shared videos showing part of the attacks on demonstrators in Portland, Oakland, Los Angeles and Seattle, as well as threats to the journalists to keep them away from reporting the events.

And massive protests erupted in several American cities and states as well as after the killing of the African-American, George Floyd, on May 25, after the policeman Derek Chauvin kneeled on his neck for about 9 minutes while he was arrested in Minneapolis, Minnesota.

Floyd turned into an icon against racism around the world, and the slogan "Black Life Important" was raised, the issue remained interactive and daily demonstrations persisted.
