Drought hits Ethiopia

Aid agencies are warning that Ethiopian authorities are under-estimating the scale of the country's drought.
Official estimates of the number of people facing hunger and hardship stand at 4.6m but agencies warn the real figure could be more than 8m.
There is also confusion over the amount of money needed to meet the crisis, with the Oxfam agency estimating it at about $500m.
However, the United Nations reports that $772m has already been pledged.
