Support is building among Africa and Caribbean nations for the creation of an international tribunal on atrocities dating to the transatlantic trade of enslaved people, with the United States backing a U.N. panel at the heart of the effort.

A tribunal, modeled on other ad-hoc courts such as the Nuremberg trials of Nazi war criminals after World War II, was proposed last year. It has now gained traction within a broader slavery reparations movement, Reuters reporting based on interviews with a dozen people reveals.

Formally recommended in June by the U.N. Permanent Forum on People of African Descent, the idea of a special tribunal has been explored further at African and Caribbean regional bodies, said Eric Phillips, a vice-chair of the slavery reparations commission for the Caribbean Community, CARICOM, which groups 15 member states.
