Hundreds of people are expected to attend a memorial in Minneapolis for African American George Floyd, who died in police custody last month.
The death of Floyd, whose neck was pinned under a white officer’s knee, has sparked huge protests over racism and police killings of black Americans.
The tribute comes despite fears over coronavirus at large gatherings.
New charges were announced on Wednesday against all four of the now sacked officers present at Floyd’s death.
The charge against Derek Chauvin has been elevated to second-degree murder while the other three officers, previously uncharged, face counts of aiding and abetting murder.
The vast majority of demonstrations over the past eight days have been peaceful, but some have turned violent and curfews have been imposed in a number of cities.
Former President Barack Obama and Meghan, the Duchess of Sussex, are among senior public figures who have offered their support to the protesters.
They were joined on Wednesday by former Defence Secretary James Mattis, who also attacked his former boss President Donald Trump, saying that he stoked division and had abused his authority in his reaction to the protests.
What will happen at the memorial?
The event, in the northern city of Minneapolis where Floyd died, is the first of several to honour him.
It will take place at a sanctuary at the city’s North Central University.
Benjamin Crump, a lawyer for the Floyd family, said it was more than just honouring the dead man’s memory.
“It’s going to be a celebration of life, but it’s also going to be a plea to America and a plea for justice that we don’t let his death be in vain,” he told NBC’s Today show.
Veteran civil rights campaigner, Rev Al Sharpton, will deliver the eulogy for the two-hour service, which will start at 13:00 local time (18:00 GMT).
“Out of all the years that I’ve been marching and protesting and doing eulogies and speeches, I’m more hopeful going to this service than I have been in a long time,” Rev Sharpton said on MSNBC’s Morning Joe programme.
“Because I see more Americans of different races and different ages standing up together, marching together, raising their voices together… That makes me know we’re on the brink of real change.”
Rev Sharpton, who met Floyd’s family on Wednesday, said he would announce the launch of a new social movement at the memorial, as well as call for new federal legislation to end racial discrimination by police.
Further tributes will be held at Floyd’s birthplace in North Carolina on Saturday, and in his home town of Houston on Monday.
