Concern continued to mount this week over increased displacement and a deteriorating humanitarian situation in Darfur, western Sudan. The UN warned that the situation in Darfur may emerge as the worst humanitarian crisis in Sudan since 1998, owing to rising displacement and declining access to the area because of insecurity. In a statement, the UN Office for the Coordination of Humanitarian Affairs (OCHA) said that insecurity had continued to cause displacement of hundreds of thousands of people and had hampered relief operations.
