The UN will have prime responsibility for police operations in Timor Leste. This is the first ever such arrangement between a sovereign nation and the UN. The UN is to restore and maintain public security, and to assist with the reform, restructuring and rebuilding of the Timorese National Police, and the strengthening of the Ministry of the Interior. Violence this year has led to the deaths of at least 37 people and forced 15% of the population to flee their homes.
