Mothers in a displacement camp in southern Somalia struggle to keep their children alive as drought and aid disruptions deepen hunger, a crisis that now also has a link to the far-away Iran war. On Wednesday, UNICEF chief Catherine Russell visited the Ladan camp in the town of Dollow, to see the situation first-hand. Russell and aid workers say the war has sent shockwaves, caused shipping delays and threatened supply lines because of soaring fuel prices. The U.N. children's agency says it has lifesaving supplies in transit, but shipments now look uncertain and stocks could run out by late April. Hospital staff say they now treat children in extreme condition.

Unicef, the United Nation's fund for children, reported it raised $7.5 million since Sunday for tsunami victims in south Asia.
