UNICEF chief urges world to prevent a 'human catastrophe' in Central African Republic

The head of the U.N. children's agency is urging the international community to do everything it can to prevent the "human tragedy" in Central African Republic from turning into "a human catastrophe."

Anthony Lake made the appeal Tuesday as the U.N. World Food Program announced there are only food supplies for a week available in the capital, Bangui, and the U.N. humanitarian office said it has received just $60 million of the $551 million it appealed for to help thousands in need.

Lake urged countries that pledged $300 million for the country in Addis Ababa, Ethiopia on Saturday to come up with the money quickly.

Central African Republic has been in chaos since a March 2013 coup. The violence that erupted in December has increasingly targeted civilians of Muslim origin.
