For some, the death of George Floyd has clear parallels with that of Adama Traoré in France.
It happened during a protest over racism and police violence after the death of George Floyd.
Attendees at the first of several funerals to be held across the US for George Floyd stood in silence for 8 minutes, 46 seconds, the amount of time Floyd was alleged to be on the ground under the control of police.
"You've communicated a sense of urgency," former US President Barack Obama told young protesters, calling protests over the death of George Floyd "powerful".
"Donald Trump is the first president in my lifetime who does not try to unite the American people —does not even pretend to try. Instead, he tries to divide us," said Mattis, who served as Trump's defence secretary from 2017-2019.
