However, Majdalani said Israeli measures on the ground, including building settlements in the West Bank and East Jerusalem, and "procrastinations" are making the solution "more difficult."

After nearly 15 months of stagnation, Israel and the PNA started indirect negotiations in May under the U.S. pressure. PNA refused to hold face-to-face talks with Israel as the latter insists on building settlements on lands that would be the future Palestinian state.

Majdalani said the proximity negotiations, led by Washington, would last for four months "and then the available options would be examined after the situation is studied comprehensively."

PNA had threatened last November to go to the UN Security Council to snatch an international recognition of a Palestinian statehood in the Gaza Strip, the West Bank and East Jerusalem.

The final-status negotiations, which tackle thorny issues like borders, security, refugees and prisoners, should have been completed three years after the establishment of the PNA according to Oslo accord.

Fatah party, led by President Mahmoud Abbas, is not willing to dismantle the PNA "because it is the fruit of a big national struggle," said Jamal Muhissen, a member of Fatah central committee.

Fatah "hasn't discussed that option which needs an in-depth study and intensive consultations with the Arab countries," said Muhissen, stressing that Fatah is still supporting the proximity negotiations.

Many Palestinians believe that the PNA is the seed of the future Palestinian state.

For Hamas, the Islamic movement which swears to destruct Israel, the PNA "reached a dead end by betting on an agreement with Israel and by counting on the United States as a mediator," said Hamas spokesman Fawzi Barhoum.

Barhoum, whose movement routed pro-Abbas forces and took over Gaza in 2007, urged the PNA "to prefer national unity and restore dignity to the resistance by halting all forms of negotiations with Israel."

All the options the PNA have "are difficult, narrow" and can't be considered with the division between Hamas and the PNA, said Al- Massri.
