Man opens fire on Portland street as Antifa protesters clashed with Proud Boys

Dramatic footage showed a gunfight erupt in downtown Portland after Antifa demonstrators returned fire at a man who shot at them with a handgun.

That unidentified man was filmed standing behind a trash can before firing a single shot from a handgun on Sunday. Moments later unseen Antifa protesters returned fire, The Guardian reported.

The violent scene erupted at the same time as the Oregon city was playing host to a Summer of Love conservative event said to have been attended by far-right groups including the Proud Boys.

That event - held in the parking lot of an abandoned suburban K-Mart-  turned violent after 30 far-left Antifa members clad in dark 'black bloc' attire walked past the K-Mart, prompting the Proud Boys to give chase.
