A memorial service was underway on Thursday in Minneapolis for George Floyd, the African-American man whose videotaped death while being arrested has sparked nationwide protests. Members of Floyd's family, the Reverend Jesse Jackson, Minnesota Governor Tim Walz, Minnesota Senator Amy Klobuchar and Minneapolis Mayor Jacob Frey were among several hundred people attending the service at North Central University in downtown Minneapolis. Civil rights activist Al Sharpton is to deliver the eulogy for the 46-year-old Floyd, who is to be buried in his home town of Houston, Texas. Four police officers have been arrested for their role in Floyd's death, which has unleashed a wave of protests for racial justice unseen in the US since the 1968 assassination of Martin Luther King Jr. cl/jm
