The number of internally displaced persons (IDPs) in the camps is growing rapidly as thousands of civilians leave the conflict zone. The United Nations (UN) has stated that approximately 280,000 people have now been security screened and registered. IDPs are currently accommodated in 41 sites situated in Vavuniya, Jaffna and Trincomalee. The UN has generally had better access to the camps than NGOs, particularly in Jaffna.
