Israel's U.N. mission hears from families of kidnapped, missing: "We want them back. It's all we want. "

At a standing-room-only meeting at U.N. headquarters in New York, Israel's U.N. mission heard heart-wrenching accounts from families of Israelis, Americans and others believed to have been kidnapped by Hamas during its attack on Israel last Saturday.

"We experienced our darkest moment since the Holocaust," Israel's U.N. Ambassador Gilad Erdan said, adding, "Men, women, children, the elderly, not even newborn babies were spared. Entire communities have been erased. The savagery is unfathomable."

The first family member to speak was Yoni Asher, joining virtually from Israel. His wife Doron (who has German citizenship); their two young daughters, Raz and Aviv; as well as his mother, his mother-in-law and her husband were all taken hostage by Hamas.
