Gaza (CNN) - Hamas and Israel blamed one another Tuesday for the lack of a cease-fire in a conflict that has left more than 1,200 people dead, raising questions about just what it will take to end the fighting in Gaza.
International efforts to broker a deal to end the violence failed again, with Hamas rejecting a cease-fire proposal put forward by the Palestinian Authority that called for a 24-hour truce that could be extended to 72 hours. Hamas maintains that any deal must include an end to Israel's blockade of Gaza.
Israeli Prime Minister Benjamin Netanyahu has said any truce must allow for its protection against tunnels used by Palestinian militants in Gaza to make their way into Israel.
"Hamas is responsible for all deaths on their side and on our side because they are the ones who kept this conflict going," Mark Regev, a spokesman for Netanyahu, told CNN.
