The head of Save the Children described in horrific detail Wednesday the slow agony of starving children in the Gaza Strip, saying they are so weak, they do not cry.

Addressing a U.N. Security Council meeting on the Israeli-Palestinian conflict, the president of the international charity, Inger Ashing, said famine — declared by the U.N. last week to be happening in Gaza — is not just a dry, technical term.

"When there is not enough food, children become acutely malnourished, and then they die slowly and painfully. This, in simple terms, is what famine is," said Ashing.
