The United Nations said on Tuesday that its flash appeal for more than $600 million to support the humanitarian response in Afghanistan until the end of the year was now fully funded. According to the UN, Afghanistan is on the brink of a humanitarian catastrophe, with more than half of its population at risk of not having enough to eat during the coming winter. Following the Taliban takeover of the country in August, the UN held a ministerial meeting in Geneva in September, asking international donors for urgent support.
