The military wing of Hamas, Izzedine al-Qassam said the Egyptian brokered truce deal "does not deserve the ink it was written with".
The deal promises to ease the border blockage to Gaza, but such promises were part of the 2012 truce and were quickly broken as violence flared.
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.
An easing of the blockade is key to the survival of Hamas, and a recent closure by Egypt has prevented cash and goods from coming into the strip through hundreds of smuggling tunnels under the Gaza-Egypt border.
It's been an emotionally exhausting day in Israel and Gaza as hopes for peace were raised then dashed then raised then dashed again.
In the court of international opinion, this is how Israel wins a battle and still manages to lose the war.
Until the Israelis and the Palestinians find a way of resolving the underlining conflict this will not be more than a pause.
