In other news, Israel declared a unilateral ceasefire on Saturday, ending a twenty-two-day assault on Gaza that killed more than 1,300 Palestinians, most of them civilians and at least one-third children. Hamas followed with a declaration of a one-week ceasefire until Israel withdraws all its troops. Thirteen Israelis died during the twenty-two-day war, including four Israeli soldiers by friendly fire. Israel called off its attack after the Bush administration signed a deal promising increased US cooperation in halting arms smuggling into Gaza. The incoming Obama administration also backed the agreement.
