Four soldiers with the South Sudan People's Defence Forces (SSPDF) were on Sunday shot dead by UPDF soldiers following a clash at Maru village in Yumbe District.
According to Mr Yusuf Taban, the LC1 chairman of Maru, the armed South Sudanese soldiers had been harassing locals from May 20 to May 30 when the UPDF got involved.
He added: "Following a public outcry, the UPDF soldiers at Goboro detach Parish in Yumbe District launched an operation at Fitinambaya trading centre in Maru village on May 30 that ended with the killing of the four soldiers during an exchange of gunfire."
He explained that there were South Sudanese soldiers established at Goboro detach near Fitinambaya trading centre on South Sudan side, making it easier for them to cross over and attack people.
Mr Leuben Ndifula, the UPDF public relations officer for West Nile, said Ugandans were harrased by some groups of armed people from South Sudan especially in the areas of Goboro.
