A senior Israeli government official warned that Israel would strike Gaza even harder if Hamas does not accept the truce.
Israel has carried out hundreds of air strikes against targets in Gaza in the past week and amassed troops on the border of the coastal strip, but has so far refrained from a ground offensive that could quickly drive up the casualty count on both sides.
A group of senior Israeli Cabinet ministers accepted the offer today, according to a statement by the office of Prime Minister Benjamin Netanyahu. A senior government official told The Associated Press after the announcement that Israel would step up its military offensive if Hamas rejects the offer.
"As you know, the Cabinet has accepted the Egyptian proposal. If Hamas rejects it, Israel will continue and intensify its operations and Hamas will find itself totally isolated, including in the Arab world, which supports the proposal," said the official, speaking on condition of anonymity because he was not authorized to talk to the media.
The military wing of Hamas, Izzedine al-Qassam, said in a statement on the Hamas website that the proposal "does not deserve the ink it was written with."
Hamas officials are weary of promises by Egypt and Israel to ease the border blockade. Such promises were also part of a truce that ended more than a week of fighting in 2012, but were quickly broken as violence flared again.
"It's not logical to ask people who are under aggression to cease fire and then later to negotiate terms that were not respected in the past by the Israelis," he said, referring to the 2012 truce.
Meanwhile, US Secretary of State John Kerry, who was in Vienna for negotiations over Iran's nuclear program, decided not to make an immediate trip to the Middle East today to push diplomatic efforts toward the Israel-Hamas cease-fire.
