Organisers of the letter of this group of Black Muslims say it is the latest effort in what is a long and deep-rooted history of Black-Palestinian solidarity.

"Black communities have fought tirelessly against slavery, against segregation, against racial violence, so it recognises the Palestinian struggle is the same fight for freedom, for dignity and the right to self-determination," Abdullahi said.

"Just as Jim Crow saw the South try to keep the Black community subjugated, we're seeing Palestinians undergoing that, Israel using their apartheid system to strip them of their land, of their rights. It goes beyond solidarity."
