The United Nations says 62 people have been killed and thousands forced from their homes since the start of the year by flooding in northern Namibia.
In a statement Wednesday, the U.N. children's fund says the numbers could "dramatically increase" soon.
U.N. officials in Namibia say a new wave of water is expected from Angola, and the forecast is for more rains in northern Namibia in the coming days.
UNICEF says northern Namibia is already vulnerable. It is among the most densely populated and poorest parts of the country, with a high number of people carrying the AIDS virus. UNICEF says one in every fifteen children dies before reaching the age of five in the region.
