As the ongoing U.S.-mediated peace talks between Israel and the Palestinians continue to falter, a Palestinian official said Sunday that any extension of the negotiations must include demands on Israel.

"A full halt of Israel's settlement activity and the release of Palestinian prisoners in Israeli jails are our conditions to extend the peace negotiations," Nabil Shaath, a central committee member of the Fatah movement, told state-run Voice of Palestine radio.

On Saturday, a Palestinian official, who spoke to Xinhua on condition of anonymity, said there might be a conditional extension of the current peace talks which are set to end this April.

Shaath expressed doubt the U.S. President Barack Obama will pressure Israeli Prime Minister Benjamin Netanyahu to make any breakthroughs in the peace process during their meeting in Washington on Monday.

Obama is set to meet with the Palestinian President Mahmoud Abbas in mid-March to discuss the faltering peace negotiations. In late February, a Palestinian official said Abbas originally dismissed the idea of extending the nine-month peace talks with Israel when asked about it by U.S. Secretary of State John Kerry, saying that the negotiators needed to solve problems within the remaining time.

However, Sunday's statements may signal that Palestinian leadership is open to putting off the deadline if it will give them more leverage.

Since the resumption of the Palestinian-Israeli peace negotiations last July after a three-year halt, the U.S. has been working to narrow the gaps between the two sides on a framework plan for peace that could end their prolonged conflict.

Ten days ago, Abbas and Kerry held talks in Paris in which Kerry presented his ideas for a possible peace deal.

However, Palestinian officials said Kerry's proposals fell short of Palestinian demands and were biased in favor of Israel.

Palestinians are seeking an independent state in the territories Israeli occupied in 1967, including East Jerusalem as the capital of their future state.

They also want a fair solution to the issue of refugees, who fled their homes during the Palestinian-Israeli war in 1948, and to the issue of Jewish settlements that dot the Palestinian West Bank. Endi
