The United States has imposed financial sanctions on one of the vice presidents of South Sudan for his involvement in human rights abuses.
A statement from the US treasury says Taban Deng Gai arranged the disappearance and deaths of the human rights lawyer, Samuel Dong Luak, and an opposition politician, Aggrey Idry.
It said he did this in order to strengthen his position within the opposition party, the SPLM-IO.
In 2018 President Salva Kiir and the rebel leader Riek Machar signed a peace deal aimed at ending a civil war that displaced almost four million people.
There is however growing international concern that the deal could still unravel as a unity government has still not been formed.
