The United Nations appealed Tuesday to the air transport industry to help fly food in urgently to the Horn of Africa, where millions of people are starving due to a severe drought. "We're making an appeal to the air transport industry for free and heavily discounted cargo space to help us transport emergency nutrition supplies to the Horn of Africa," said Marixie Mercado, spokeswoman for the UN children's agency. British Airways, Lufthansa, Virgin Atlantic [joint venture Virgin Group & Singapore Airlines] and UPS have all offered to transport between 15 and 50 metric tonnes a week, but UNICEF is "looking to others to step forward as well."
