The announcement came hours after Israeli Prime Minister Benjamin Netanyahu vowed to destroy Hamas' tunnel network with or without a cease-fire as the Palestinian death toll soared past 1,400. In a statement released in New Delhi where Secretary of State John Kerry is traveling, the U.S. and United Nations said they had gotten assurances that all parties to the conflict had agreed to an unconditional cease-fire. At least 1,441 Palestinians have been killed, three-quarters of them civilians, since hostilities began on July 8, according to Gaza health officials - surpassing the at least 1,410 Palestinians killed in 2009, according to Palestinian rights groups.
