UN aid agencies at their daily press briefing in Amman on 2 April reported 'an improving pattern of access' for humanitarian supplies. The first convoy of trucks is heading to Safwan, south of Basra, the UN Children's Fund (Unicef) reported, each carrying 35,000 litres of drinking water and emergency health kits. Unicef spokesman Geoffrey Keele said that staff delivering aid to Zubair on 1 April had reported children already suffering through the intense heat, and said that the net effect of current conditions was 'crippling'. The International Committee of the Red Cross told journalists that electricity supplies to western Iraq had been cut off since 29 March, and that water treatment facilities, operating on back-up generators, were functioning at about 40 per cent capacity. The UN High Commissioner for Refugees said that numbers fleeing Iraq remained small, and consisted mainly of foreigners seeking to return home.
