US Secretary of State John Kerry called peace Justice Minister Tzipi Livni and Palestinian leader Mahmoud Abbas to voice his concern about the three yeshiva students Friday night, 24 hours after they went missing near Hebron and feared kidnapped by Palestinian terrorists. There is still no word of their fate, despite the ongoing large-scale intensive hunt by the Israeli military, Shin Bet and police. One of the missing 16-year olds is an American citizen.
