Tens of thousands of civilians trapped inside rapidly shrinking areas of combat between government forces and the Liberation Tigers of Tamil Eelam (LTTE) in northern Sri Lanka are a major concern for the UN, a visiting top official said. “The conflict is still going on, large numbers of people are being trapped in the Vanni [combat zone],” Walter Kaelin, the Representative of the UN Secretary-General for Human Rights of Internally Displaced Persons (IDPs), told reporters in the northern town of Vavuniya on 4 April. [...] On 3 April, World Food Programme (WFP) dispatched 1,000MT of food into the combat zone, the single largest shipment since the sea convoys began. WFP stated in a press release that since February 2009, more than 2,200MT of supplies - sufficient to feed 132,000 people for 20 days - had been sent to the combat zone with the assistance of the government in ships flying the ICRC flag.
