The programme was temporarily halted on 17 March after the withdrawal of all UN staff from Iraq on the eve of hostilities. The Security Council adopted a resolution on 28 March giving the UN more authority to administer the operation until 12 May. The authority included prioritising deliveries and finding new entry ports to speed shipment. The three week extension was approved at the end of April
The UN Office of the Iraq Programme (OIP), which oversees the programme under which Baghdad was allowed to use part of its oil revenues to buy food and humanitarian supplies, said on 20 May that most of the supplies were for food ($463 million), electricity ($239 million), agriculture ($119 million) and health ($88 million).
