Israel's prime minister says Israelis must be ``ready for a prolonged campaign'' against Hamas in the Gaza Strip.
Benjamin Netanyahu also said in a televised speech Monday that a demilitarization of Gaza must be part of any future solution in the territory.
Meanwhile, a strike on a Gaza park killed 10 people, nine of them children. Israeli and Palestinian authorities traded blame over the attack as fighting in the Gaza war raged on despite a major Muslim holiday.
A truce between the sides remained elusive as diplomats sought to end the fighting at the start of the Eid al-Fitr holiday, marking the end of the Muslim holy month of Ramadan.
