Egyptian President Mohammed Morsi called Thursday for an emergency meeting of the U.N. Security Council to discuss Israeli attacks on Gaza.
Israel said strikes in Gaza Wednesday, including one in which a top Hamas official was killed, are part of a campaign against Hamas and Islamic Jihad in Gaza.
Egyptian intelligence officials were trying to defuse the escalating violence between Israeli forces and Palestinian militants, Haaretz reported Sunday night.
Hamas political leader Khaled Mashaal has decided against running for re-election after 16 years in the post, the militant Palestinian group said.
Palestinian Hamas leaders denied a report that exiled leader Khaled Mashaal ordered the party's armed wing to stop attacks against Israel.
Palestinian Authority President Mahmoud Abbas says he will call for elections if negotiations with Hamas militants don't produce results soon.
Palestinian militants said Monday they would exact revenge against the "Zionist enemy" in response to an Israeli attack on a house in Gaza.
Hamas has begun evacuating its Gaza offices and security sites in preparation for an anticipated counterattack from Israeli forces for a recent rocket attack.
Hamas is not gaining any ground, despite the perception the Palestinian party is trying to create, Israel's vice prime minister said Saturday.
The Egyptian government has convinced several Palestinian factions, including Hamas, to begin talks aimed at limiting the widespread violence in the Mideast.
