Palestinian President Mahmoud Abbas' Fatah party and its rival the Islamic Hamas movement will no longer hold reconciliation talks and will wait for an announcement of a deal, a Fatah official said on Wednesday.

"There will be no sixth session of the Egyptian-hosted mutual talks between Hamas and Fatah and the role of the negotiators has ended," said Ibrahim Abu al-Najja, a Fatah leader in the Gaza Strip.

On Monday, Fatah and Hamas ended the fifth round of unity talks in the Egyptian capital without achieving any breakthrough to bridge internal splits that have undermined hopes for peace negotiations with Israel, according to officials of both sides.

However, Egyptian mediators stepped up pressure on rival Palestinian groups to form a unity government, setting a July 7 deadline to reach a final agreement between the rival factions.

Abu al-Najja said there would be no such meetings between Fatah and Hamas before Egypt arranges meetings of five specialized committees which will form an operation room to tackle the detailed problems between Hamas and Fatah.

"Every committee will meet separately and will announce its conclusions so the Egyptians will be able to declare the final agreement which will be supported by the Arabs," Abu al-Najja added.

The five committees are respectively tasked to discuss ways to form a unity government, reform the security services, restructure the Palestinian Liberation Organization (PLO), hold elections and boost the national reconciliation.

The dialogue is aimed at reconciling Hamas and Fatah to end the aftermaths of Hamas' violent takeover of the Gaza Strip and the political schism between the Hamas administration of Gaza and the Fatah-dominated Palestinian National Authority (PNA) in the West Bank.
