In 2005 two directors of Medicine Sans Frontieres Holland in Darfur were arrested on charges of crimes against the state, publishing false reports and spying. Their crime was the release of a report on the prevalence of rape and the many cases they had treated in the region. The Khartoum regime denies that rape occurs in Darfur. The head of MSF Holland refused to participate in the prosecutions of the two MSF workers and so she was expelled from Darfur. The head of OCHA was also expelled this year. If aid workers speak out, they face reprisals or expulsion. The result is a terrible silence . Here is a striking example: the most recent reports on malnutrition rates in Darfur were released last September. They revealed that in some of the camps, 30-40% of the population is suffering from acute malnutrition. In the past nine months, access to displaced people has shrunk, while levels of violence have risen. Food rations have been reduced by almost by 50% . Unquestionably this has taken a further toll on the anguished people of Darfur, especially the most vulnerable, the children under five. But no new malnutrition surveys have been made public. The government of Sudan is refusing to authorize their release. This is an outrage.
