UN launches urgent Ebola aid appeal UN Secretary General Ban Ki-moon has launched another urgent appeal for funds to help fight Ebola after a UN drive for donations fell short of its target. The UN chief said a $ 1 billion trust fund he launched in September has received just $ 100,000 so far. He joins a growing chorus of world leaders criticising global effort to tackle the Ebola outbreak. The disease has killed about four thousand 500 people mostly in Liberia, Guinea and Sierra Leone. Although several countries across the world have pledged to support the struggle to contain Ebola, few have matched their pledges with donations. Donors have given almost 400million dollars but the trust fund itself has received pledges of just 20million dollars and only Colombia has paid so far. BBC
