Demonstrators are calling for the end of gun violence on the streets of Harlem.
The National Action Network joined other activists Saturday for a march to call for peace and unity.
The event highlighted gun violence among minorities and in the LGBTQ community.
It coincided with Gun Violence Awareness Month, Pride Month and the 50th anniversary of the June 1969 Stonewall uprising.
Participants observed a moment of silence for the victims of the mass shooting Friday in Virginia Beach, where a gunman fatally shot 12 people.
The Rev. Al Sharpton condemned the recent burning of rainbow flags at the entrance of a gay bar in Harlem. He told a rally that "Harlem doesn't harbor homophobia."
Police are investigating that incident as a possible anti-gay bias crime.
