Five suspects have been charged over an attack on a white couple at a jazz festival in Cincinnati.

Violent footage showing a man and woman being beaten by a group of people in the Ohio city on Saturday went viral on social media over the weekend, prompting condemnation from figures including JD Vance, the US vice-president.

On Monday, police charged five suspects over the attack, but did not release their names. They said they expected to bring more charges and are in contact with the victims.

Harmeet Dhillon, a senior figure in the US justice department, suggested the attack on the white couple may have been motivated by race, and that suspects could also be charged with federal hate crimes.

Video shared on social media shows the fight apparently break out after a white man reaches out to slap a black man dressed in a red t-shirt while the pair argue surrounded by a group.
