Israeli Defence Minister Moshe Yaalon said on Saturday Mahmud Abbas was "not a partner for a final peace deal" as the Palestinian leader prepared to meet US President Barack Obama.

Abbas "is a partner for receiving, not giving," Yaalon told Israel's Channel 2 television in an interview.

"He is not a partner for a final agreement that would include the recognition of Israel as the national state of the Jewish people and that would end the conflict and all claims."

Abbas is due to meet Obama in Washington on Monday to discuss the stalled direct peace talks brokered by US Secretary of State John Kerry.

Palestinian and Israeli leaders have been locked in talks launched last July after a three-year hiatus, but the negotiations have faltered.

"He (Abbas) says it very clearly but no one seems to listen... I'm sorry to come to this conclusion, but this (deal) will not happen in my time," said Yaalon who is considered to be one of the most rightwing ministers in Prime Minister Benjamin Netanyahu's coalition government.

The Abbas-Obama talks are likely to focus on a US-proposed framework to guide final status negotiations, before the impending deadline for the current round of talks on April 29.

Last week Netanyahu meet Obama, who urged him to take "tough decisions" and warned that Israel would be exposed to further international isolation should the talks fail.

Yaalon also criticised Kerry in veiled terms on the issue of the release of Palestinian prisoners that Israel is engaged to do under the current talks.

"We are committed to the release of prisoners held since before the Oslo Accords, not the release of Israeli Arab prisoners," he said.

He was referring to the fourth and final phased release of long-serving prisoners scheduled for March 29 -- a commitment Israeli ministers have hinted may not be met.

"What happened happened in Kerry's mediation," Yaalon said.

"I don't want to go into details, it is between him and us. He knows we are not committed to the release of Israeli Arabs," he said.

Abbas to meet Obama ahead of peace talks deadline
Ramallah, Palestinian Territories (AFP) March 15, 2014 - As Palestinian president Mahmud Abbas prepares to touch down in Washington for a meeting on Monday with Barack Obama, an extension of peace talks with Israel looks far from certain.

Palestinian and Israeli leaders have been locked in talks US Secretary of State John Kerry fought hard to launch in July after a three-year hiatus, but as negotiations have faltered, Israel has kicked up more obstacles to a peace deal that would end decades of conflict.

Kerry hopes the two sides will agree on a US-proposed framework to guide final status negotiations, before the impending deadline for the current round of talks on April 29.

But he is aware of the danger posed to talks by a recently-concocted Israeli demand -- that Palestinians recognise Israel as a Jewish state -- and came out strongly against Prime Minister Benjamin Netanyahu's emphasis on it, just days before Abbas's visit.

"'Jewish state' was resolved in 1947 in (UN) Resolution 181 where there are more than 30 to 40 mentions of 'Jewish state,'" Kerry testified at a Congressional hearing Thursday, adding late Palestinian leader Yasser Arafat had already accepted the idea of a Jewish state in principle.

"I think it's a mistake for some people to be raising it again and again as the critical decider of their attitude toward the possibility of a state and peace, and we've obviously made that clear," Kerry said, referring to repeated statements by Netanyahu, who himself visited the White House on March 3.

Current Palestinian leaders have opposed recognising Israel as a Jewish state, fearing this could threaten the rights of non-Jewish Arabs living in Israel, who make up some 20 percent of the population, as well as other religious minorities.

And even without the "Jewish state" stumbling block, it is unclear whether the Palestinians would accept an extension of negotiations, with Abbas saying cautiously that they will only decide if the US framework is acceptable once they have seen it.

"Until now, we haven't received the framework agreement we were promised," Abbas said at a Thursday news conference alongside visiting British Prime Minister David Cameron.

"When the framework is presented to us, we'll give our opinion on it," Abbas said.

"We have never discussed prolonging the negotiations at all, nor was it offered to us," he added.

Both Kerry and Cameron cited what they said was deep "mistrust" between Israeli and Palestinian leaders, but expressed hope Abbas and Netanyahu would soldier on towards an elusive peace deal.

"As for the question of mistrust between Palestinian leadership and Israeli leadership... what I've seen over the last few days is serious disagreements on vital issues that will have to be settled if there ever is to be... a peace deal," Cameron said.

Meanwhile, Kerry said there were "gaps... some of them very significant", but stressed these should be seen within the context of the negotiations, saying: "I still believe it's possible, but difficult."

"Certain narrative issues are so powerful and so difficult that neither leader is going to definitively cede on them at an early stage of the negotiation," Kerry conceded.

The issues include the contours of a future Palestinian state, refugees, the fate of Jerusalem, security and mutual recognition.

The Palestinians want borders based on the 1967 lines from before the Six-Day War, when Israel captured the West Bank, including now-annexed Arab east Jerusalem. They have also insisted there should be no Israeli troops in their future state.

But Israel wants to retain existing settlements it has built inside occupied Palestinian territory over the past decades. It also wants to maintain a military presence in the Jordan Valley, where the West Bank borders Jordan.

The Palestinians are also awaiting the release late March of a final of four batches of long-serving prisoners by Israel -- a commitment that Israeli ministers have hinted might be shirked.
