(CNN) – Like their Israeli counterparts, Palestinian officials say they are very concerned with Hamas' public announcement that it will not extend the cease-fire, and is "ready for a long war," as a Hamas spokesman said Thursday.
"I'm not only concerned because of what Hamas had said. I'm concerned that (Israeli Prime Minister) Benjamin Netanyahu has not scored enough points for him to win victory on the ground," said Dr. Sabri Saidam, former adviser to Palestinian President Mahmoud Abbas.
"I think he will resume the attack on Gaza because he wants to win the next elections," he said. "The tunnels are not finished. The rockets are not finished. He would want to go back and score more points, kill more people, demolish more of Gaza, and get the victory he wants."
The Palestinian authority Fatah, Egypt, and Israel want this cease-fire to continue unconditionally. Hamas does not seem to want to extend the truce unless their demands are met.
But Saidam said the Palestinians have a "united delegation" in Cairo, which includes the militant groups Hamas and Islamic Jihad.
"The message to the international community (is) that Israel is running the longest occupations in modern time and annexing more and more land as we speak," he said.
"The end to occupation will mean peace for Israel, and security for its citizens," Saidam said.
