In July and August the ICRC continued its attempts to implement an aid programme for the victims of the conflict situation in southern Sudan. An ICRC team went to Wau on 31 July to organize an airlift. Forty tonnes of relief supplies were transported on board three flights from Entebbe (Uganda) to Wau on 14 and 15 August; on the second of these two days the flights were suspended because of threats from the SPLA to shoot down any aircraft flying over the territories controlled by its troops without its authorization. The 40 tonnes of relief supplies which got through before the blockade were distributed between 19 and 22 August to starving people living in the camps for displaced people. Since the airlift was interrupted, the ICRC has made numerous approaches to the parties to the conflict, particularly the SPLA, in order to be allowed to recommence its humanitarian work.
