Twelve people deported from the U.S. arrived in Uganda on Thursday, the Uganda Law Society said, in the first known arrivals since Uganda and the U.S. signed a bilateral deal permitting the transfers.

The U.S. has struck deals with at least seven African nations to take some migrants. Those countries range from the western African nation of Ghana to the southern African nation of Eswatini, which the U.S. paid $5.1 million to take up to 160 deportees, according to details of the deal released by the U.S. State Department.

It was not clear if Ugandan authorities were similarly paid.
