In a street near the White House, protesters wrote "Black Lives Matter" (black lives matter) with yellow paint and giant letters on Friday, before massive demonstrations scheduled for Saturday to protest against racism and police brutality in the United States.

The giant inscription spanned two squares on 16th Street in the capital, and Washington DC police cleared the street so artists could complete the work.

Using buckets of yellow paint, with brushes to decorate the edges of the letters, dozens of men and women of all races and ages painted the street, pouring many of them into a sweat under the warm Washington sun.

The mayor of the capital, Muriel Bawser, said yesterday that the part located in front of the White House from 16th Street is now officially "Black Lives Mater Square".

The death of George Floyd - a black man from Minneapolis who died on May 25 after a white police officer perched on his neck - shook the country.

In addition to the massive demonstrations and violent clashes with police in the largest cities, hundreds of spontaneous demonstrations have erupted in small towns and rural areas across the country in recent days.
