If ceasefire negotiations will not include the safe return to Israel of IDF soldier Gilad Schalit, held by terrorists in Gaza for almost two years, Israel will embark on a massive operation against Hamas in Gaza, Egyptian intelligence chief Omar Suleiman reportedly conveyed to Hamas's Gaza rulers. the Lebanese Al Akhbar, newspaper quoted Palestinian sources as saying that the Hamas negotiators, shuttling between Gaza and Cairo, were willing to show some flexibility on the details of the agreement, but that their insistence to have some high profile prisoners released by Israel has prevented an agreement from being achieved.
