Black Lives Matter activists ordered white journalists and supporters to the back of their march outside the Democratic National Convention in Philadelphia.

Several videos of the protest have been posted on social media which show the female leader of the protest standing on the back of a truck while ordering racial segregation.

The un-named protester used a microphone and an amplifier to start a number of highly offensive chants aimed at the Philadelphia Police Department and Hillary Clinton.

One protester objecting to the racial segregation raised the Rosa Parks incident, but the angry woman did not respond.

Before the march set off, the woman told white people: 'Take your rightful position, behind us.'

Standing in front of a Pan-African flag, she said: 'I want to see all of the white folks at the back of the crowd.'

'White people, get to the back. Black people, come to the front.'

The woman then began pointing at individual people and ordering them to the back of the crowd during her expletive-riddled tirade.

At the same time the woman was making the highly offensive comments, the mothers of several black men shot dead were addressing the convention.

Trayvon Martin's mother Sybrina Fulton told Democrats that she supports Hillary Clinton because the presidential nominee 'is a mother who can assure our movement will succeed'.

Fulton said their group was the Mothers of the Movement.

Trayvon Martin was fatally shot in Florida by a neighborhood watch volunteer in 2012 at the age of 17. The gunman was later acquitted of second-degree murder.

Martin's mother says at the convention that Clinton 'has the compassion and understanding to support grieving mothers. She has the courage to lead the fight for common sense gun legislation'.
