 A video published by the Israeli Army shows soldiers getting ready for mobilization on Saturday following a surprise attack by members of the Islamist group Hamas that killed at least 40 people and wounded hundreds. The attack, biggest against Israel in years, combined gunmen crossing into Israel with a barrage of rockets fired from Gaza. Israel said the Iran-backed group had declared war as its army confirmed fighting with militants in several Israeli towns and military bases near Gaza and Prime Minister Benjamin Netanyahu vowed to retaliate.
