Barack Obama urges Mid-East leaders to take opportunity
US President Barack Obama has urged Israeli and Palestinian leaders not to let the chance of a permanent peace deal "slip away".
"This moment of opportunity may not soon come again," he said, pledging US support for the new negotiations.
Mr Obama spoke the day before a new round of direct talks between Israeli PM Benjamin Netanyahu and Palestinian leader Mahmoud Abbas was due to begin.
Earlier, he condemned the "senseless slaughter" of four Israeli settlers.
They were shot dead by gunmen near the West Bank city of Hebron on Tuesday, with the armed wing of Islamist movement Hamas, which controls the Gaza Strip and opposes peace talks with Israel, saying it had carried out the attack.
And in another attack, two Israelis were shot and wounded on Wednesday in the West Bank at Rimonim Junction, near the Jewish settlement of Kochav Hashahar.
'Partners in peace'
Mr Obama spoke at the White House on Wednesday evening after meetings with Mr Netanyahu, Mr Abbas, Jordan's King Abdullah II and Egyptian President Hosni Mubarak.
His remarks came on the eve of the first direct negotiations between Israeli and Palestinian leaders in 20 months, which he said were "intended to resolve all final status issues".
Mr Obama said the goal of the talks, which are expected to last a year, was a permanent settlement that ended the Israeli occupation that began in 1967 and resulted in an independent, democratic Palestinian state existing peacefully beside Israel.
He said the US could not impose peace on the two parties, and that the US could not want peace more than them.
And he praised Mr Abbas and Mr Netanyahu as leaders "who I believe want peace".
But he warned of "extremists and rejectionists who, rather than seeking peace, are going to be seeking destruction."
In remarks ahead of a Wednesday evening dinner with the Arab leaders, Mr Netanyahu described Mr Abbas as his "partner in peace", and said he would not allow the latest attacks to "block our path to peace".
"Our goal is to forge a secure and durable peace between Israelis and Palestinians," he said.
"We do not seek a brief interlude between two wars. We do not seek a temporary respite between outbursts of terror. We seek a peace that will end the conflict between us once and for all."
Speaking next, Mr Abbas condemned attacks on Israelis and urged an end to bloodshed.
On Wednesday, an Israeli man and woman were shot and injured in the second attack in the West Bank in 24-hours.
Israeli army radio reported that the injured Israelis were travelling in a car near the Jewish settlement of Kochav Hashachar, to the east of Ramallah, when their car was overtaken by another vehicle, from which shots were fired.
The man is in a serious condition in hospital, Israeli officials have said
The militant wing of the Islamist group Hamas has claimed responsibility for both this latest incident and the shooting dead of four Israelis in the West Bank on Tuesday.
'Elephant not in the room'
The BBC's Jon Donnison in the Gaza Strip says that as the peace talks get under way in Washington, Hamas seems to be sending out a message that it is not to be ignored.
The Islamist movement is the elephant in the room, or rather not in the room, our correspondent says. Despite controlling Gaza, Hamas is excluded from the talks because Israel, the US and European Union do not recognise its authority.
As a result Mr Abbas, a rival of Hamas, will be negotiating in the talks over territory that he does not even control, namely the Gaza Strip.
It is hard to see how there can be peace between Israelis and Palestinians, unless Fatah and Hamas sort out their differences first, our correspondent says.
Speaking in Washington, Mr Abbas also called for a freeze in Jewish settlement construction in the West Bank, and said it was time to end the Israeli occupation of Palestinian land that began in 1967.
"We will spare no effort and we will work diligently and tirelessly to ensure these negotiations achieve their cause," Mr Abbas said.
King Abdullah said the group needed Mr Obama's "support as a mediator, honest broker and a partner".
"If hopes are disappointed again, the price of failure will be too high for all," he said.
Disagreement over Israeli settlement construction in the occupied West Bank has also threatened to cast a pall over the talks.
The Israelis have said they will not renew a partial freeze on building homes for Jewish settlers when it expires towards the end of this month, but the Palestinians say that without a freeze they will walk away from the talks.
On Thursday, US Secretary of State Hillary Clinton is to hold discussions with the Israeli and Palestinian negotiating teams.
Mr Netanyahu and Mr Abbas are to then meet for the first face-to-face talks between Israeli and Palestinian leaders since late 2008.
US officials said they wanted to at least get agreement from the two sides to meet again, possibly in the second week of September.
Another meeting between Mr Obama, Mr Abbas and Mr Netanyahu could be held during the UN General Assembly at the end of the month.
