United Nations ( CNN ) -- Thirty Congolese women on the border of Angola and Congo were held in a dungeonlike prison and systematically raped by uniformed men , according to U.N. officials . The Congolese women were part of a group of 150 people who had recently been expelled from Angola . The United Nations said the women reported they were held for nearly two weeks in early October and raped . The U.N. said three people in the group were killed , including two men and a woman , who died after being repeatedly raped . Those who survived and were released then returned to the Congo in the nude and with no belongings , according to the United Nations . The rapes were first reported to the United Nations on Saturday . In another region of the Democratic Republic of the Congo , Western Kasai , at least 20 Congolese women also reported being raped , the United Nations said . The U.N. Office for Humanitarian Affairs said 1,200 expulsions have been reported from Angola . While these expulsions are legal , OCHA spokesman Maurizio Giuliano said they are concerned about the human rights violations of the deportees . The organization encouraged expulsions to happen in a timely fashion with respect for human rights . U.N. officials were scheduled to meet Wednesday in the region to discuss the possibility of sending a team to investigate these claims further . These reported rapes come after nearly 500 people were systematically raped during rebel attacks this summer in the Democratic Republic of the Congo .
