The Detroit Pride parade was interrupted by a group of white nationalists from the National Socialist Movement (NSM) carrying weapons and performing Nazi salutes over the weekend.
Fox News reported that images on social media appeared to show a white nationalist ripping apart a rainbow flag and another urinating on an Israeli flag on the sidelines of the event.
According to the Hill, the Southern Poverty Law Center classifies the NSM as one of the largest neo-Nazi organizations in the country.
Several people were injured at a gay pride parade in Washington on Saturday when some in the crowd ran to escape what they thought was gunfire, and a man was later arrested when police found a firearm near him, officials said.
Police, at the outset of the incident, received a report of a man with a gun at a park, Washington police Commander Guillermo Rivera told reporters.
"As the officers were going to that scene there was a crowd of people running away from it," Rivera said. "Some of the individuals in the crowd said that there was a man with a gun and that someone had fired shots."
But police did not find any evidence of shots fired, Rivera said.
Seven people were taken to hospitals with non-life threatening injuries they sustained in the disturbance and a number of other people with minor injuries were treated at the scene, Rivera said.
