George Floyd, a black man whose death under the knee of a white police officer roused worldwide protests against racial injustice, was memorialized at his funeral on Tuesday as “an ordinary brother” transformed by fate into the “cornerstone of a movement,” Reuters reported.

During a four-hour service broadcast live on every major US television network from a church in Floyd’s boyhood home of Houston, Texas, USA, family members, clergy and politicians exhorted Americans to turn grief and outrage at his death into a moment of reckoning for the nation.
