Hamas, however, said it would continue fighting in Gaza as long as Israeli troops remained in the Hamas-ruled Strip.
"If the Israeli military continues its existence in the Gaza Strip, that is a wide door for the resistance against the occupation forces," Osama Hamdan, a Hamas official in Lebanon told Al Jazeera.
Fawzi Barhum, a Hamas spokesman, said: "The Zionist enemy must stop all its aggression, completely withdraw from the Gaza Strip, lift the blockade, and open the crossings. We will not accept the presence of a single soldier in Gaza.
