(CNN) —  

Two members of the Proud Boys have been convicted on multiple charges for assaulting members of Antifa during a fight last year.

A Manhattan jury convicted Maxwell Hare, 27, and John Kinsman, 39, on Monday, Manhattan District Attorney Cyrus Vance Jr. announced in a news release.

Both are members of the Proud Boys, a far-right extremist organization that has been designated as a hate group by the Southern Poverty Law Center. The founder of the Proud Boys is suing the Southern Poverty Law Center for designating the organization a hate group.

Hare and Kinsman were convicted of attempted gang assault in the first degree; attempted assault in the first, second and third degrees; and riot in the second degree for their part in an October 2018 brawl with members of Antifa, a left-wing anti-fascist group, the district attorney’s office said.

The fight ensued after a group of Proud Boys members left an event at the Metropolitan Republican Club. Members of Antifa were outside of the venue protesting when Hare and Kinsman taunted and threatened them, the release said. The Antifa protesters were directed away from the venue by police but then intercepted the group of Proud Boys.

Hare and Kinsman were part of a group of Proud Boys members who attacked the Antifa members, the district attorney’s office said.

The two men charged at the Antifa members “striking them with their hands, fists, feet, elbows and boots” until police arrived on scene and members of both groups fled, according to the release.

The NYPD arrested Hare and Kinsman days later. Both men are scheduled to be sentenced on October 11.

Eight other people were arrested in connection with the fight. Seven have received sentences ranging from community service to ten months in jail.

Antifa and the Proud Boys were part of dueling demonstrations in Portland, Oregon, Saturday that resulted in 13 arrests and six injuries.

People at the demonstrations were detained for a variety of charges including disorderly conduct, interfering with police, unlawful use of a weapon, and possession of a weapon on the park, Police Chief Danielle Outlaw said.
