Gunfire was heard on Thursday evening outside the Colorado State Capitol in Denver, where people had gathered for a solidarity demonstration in the support of unarmed black man George Floyd, who was killed by police.
A video that has appeared on Twitter shows people occupying the Capitol grounds, who then start rushing towards the building shortly after several shots are being heard.
According to spokesman for the Colorado State Patrol, Gary Cutler, the gunfire took place across the street from the Capitol, while another police official said that the shots were directed at the building.
