A reading at a storefront library in Providence, R.I., was interrupted on Monday night, when a group of people carrying a flag with a swastika banged on the windows of the building, shouted slurs and chanted “white power.”

The Red Ink Community Library, which describes itself as a “nonprofit community library, reading room and organizing space,” was hosting a reading of “The Communist Manifesto” by Karl Marx and Friedrich Engels for Red Books Day, celebrating the 174th anniversary of the day the manifesto was published.

In a video stream of the event, someone is seen reading from the manifesto when a sudden banging is heard offscreen, followed by a number of slurs being shouted. The person tries to continue reading, while a group is heard outside shouting slurs and “white power.”
