MSF, ICRC Leave South Sudan's Pibor Area Dimo Silva Aurelio JUBA, SOUTH SUDAN - As fighting in South Sudan's Jonglei state continues to spiral out of control, thousands of people including staff working for charity organizations have fled into the bush, forcing aid agencies to suspend operations in and around the Pibor Administrative Area. The International Committee of the Red Cross (ICRC) said Thursday it is not able to evacuate and treat the wounded due to the escalating inter-communal violence in the area. International charity Medicine Sans Frontiers (MSF), or Doctors Without Borders, said it has suspended operations in Pibor after most of its staff fled with their families. MSF and ICRC officials say they worry the sick and the wounded in the area who do not receive immediate medical attention will die. Thousands of people from the towns of Gumuruk and Manyabol have fled into the bush as the clashes approach Pibor town, some 35 kilometers away, according to Ibrahim Mohamed, MSF Belgium Head of Mission in South Sudan. .
