Egyptian officials say they have postponed reconciliation talks scheduled next week with Palestinian factions.
Authorities did not say when the Egyptian-sponsored talks would be held.
Earlier Saturday, Hamas officials said they plan to boycott the talks with rival Fatah.
Officials said Palestinian President and Fatah leader Mahmoud Abbas continues to crack down on Hamas in the Fatah-controlled West Bank.
Late last month, Mr. Abbas deployed hundreds of security officers to the West Bank city of Hebron.
Egypt invited Hamas and Fatah, along with smaller Palestinian factions, to a meeting in Cairo on November ninth to settle the conflict between the two larger groups. The factions have been divided since Hamas militants drove Fatah fighters out of Gaza in June 2007 and seized control of the territory.
