How Israel's teenagers disappeared

Israel has vowed retribution against Hamas, the militant Palestinian group it says kidnapped and murdered three teenagers in the occupied West Bank.

The bodies of Naftali Frenkel, Gilad Shaar and Eyal Yifrach were found on Monday evening, after they had been missing for more than a fortnight.
