London, June 8 (RHC)-- Scuffles have broken out between police and protesters in central London by the arches that effectively connect the Foreign Office and the Treasury. 

Objects were thrown at police lining up at the three arches that bridges the connection just off Whitehall, which is also near the offices of Prime Minister Boris Johnson.   Many of the demonstrators, who gathered earlier Sunday outside the U.S. embassy just south of the River Thames, have moved towards central London, where clashes also took place Saturday.

Anti-racism protests in Britain have been "subverted by thuggery," Prime Minister Boris Johnson has said, warning those responsible would be held to account.

Tens of thousands took to the streets of London on Sunday, rallying for a second day running to condemn police brutality after the killing of George Floyd in the United States.
