"We are also assisting the refugees who have fled across the border to Chad. As many of them have been subject to attacks by militia crossing from Sudan, UNHCR is mounting a major logistical operation to establish camps and transfer refugees away from the border zone"

In this quote, Jan Egeland is talking about the efforts being made to assist refugees who have run away from Sudan to Chad. These refugees have been targeted by militia groups crossing the border, making their situation much more dire. To address this problem, the United Nations High Commissioner for Refugees (UNHCR) is leading a large-scale logistical operation. This operation involves setting up camps and moving the refugees away from the dangerous border location. By doing so, the UNHCR wants to offer a safer and more stable environment for these displaced people. This quote highlights the importance of providing help and defense to those who have been required to leave their homes due to conflict and violence.
