Presently, about 1.5 million people in Darfur, western Sudan are homeless, hungry and vulnerable to violent attacks.  There have been widespread cases of terror, murder and rape.  Hence, these people live in perpetual fear. 
Since 2003, wars in Sudan have left about 2 million people dead, and forced 4 million people to flee their homes, leaving Sudan with the highest number of internally displaced people in the world. 
The United Nations estimates that:
49% of Sudanese refugees lack food
88% lack shelter
67% lack water
93% lack adequate sanitation! 
Compounding these problems, warring militias often rob the refugees of food. 
Conditions are extremely difficult.  Children are starving and dying of preventable disease because of very limited access to health care.
