LAGOS, Nigeria — The three Americans convicted of participating in a botched coup attempt in Congo last year have been repatriated to the United States, days after their death sentences were commuted to life imprisonment, Congo’s presidency said Tuesday.

The three will serve out their life sentences in the U.S. following the repatriation done in collaboration with the U.S. Embassy, Congolese presidential spokesperson Tina Salama said. The presidency said the Americans left Tuesday morning. International law experts say it’s unlikely the U.S. will shorten their sentences.

The State Department said it was aware of their transfer into U.S. custody and referred questions to the Justice Department.

Among the three Americans was 21-year-old Marcel Malanga, son of opposition figure Christian Malanga, who led the foiled coup attempt that targeted the presidential palace in Kinshasa. The elder Malanga, who live-streamed from the palace during the attempt, was later killed while resisting arrest, Congolese authorities said.
