Hundreds of Black Lives Matter protesters are marching on London today - here is what's happening

Close to 1,000 people gathered in central London on Sunday to march in solidarity with US "Black Lives Matter" demonstrators.

Protesters took to Oxford Street to protest the killings of two black men, Philando Castile in Minnesota and Alton Sterling in Louisiana, by police in the US this week.

Those shootings led to mass protests in Dallas that resulted in the death of 5 police, picked off by a sniper who was allegedly angry about police brutality towards African Americans.
