A United Nations aid coordination agency said Monday the drought gripping the Horn of Africa had reached a critical stage in eastern and south-eastern Ethiopia and was likely to deteriorate over the coming month, according to DPA. Ethiopia, together with Djibouti, Somalia and Kenya, is in the throes of a severe drought, that has put a total of 11 million people at risk of famine. In its latest report on Ethiopia, the UN Office for Coordination of Humanitarian Affairs (OCHA) said the situation in the south and south-east, which has been critical for two months, was likely to deteriorate given the forecast for continued dry weather. This ongoing dry spell comes during the "jilal" or small rainy season from January to March. There are also fears the drought could continue through the main rainy season or "gu" from March to May. Some two million people are affected by the drought in Ethiopia, over 1.5 million in the southern Somali region alone, with the rest mostly in neighbouring Oromia region. --More 22 04 Local Time 19 04 GMT
