Four Ugandan government officials have been suspended amid allegations of inflating refugee figures.
Uganda’s Commissioner for Refugees Apollo Kazungu and three of his senior staff are being investigated.
According to BBC News, investigations will also consider whether officials from UN aid agencies were involved.
Uganda is said to host some 1.4 million refugees – welcoming more than any other country in 2016 – mostly from South Sudan and Democratic Republic of Congo. But these allegations will cast doubts on those figures.
Until recently, Uganda had been widely praised for its immigration policies and described as one of the best places in the world to be a refugee.
