Even before peace talks with the Palestinians begin, Israel's government is fiercely debating a key concession: whether to extend a slowdown of West Bank settlement construction.

Israeli officials confirmed Monday that the government is in quiet talks with the United States in search of a "creative" solution that will allow at least some limited construction to take place after Israel's 10-month moratorium ends on Sept. 26.

The officials said Prime Minister Benjamin Netanyahu is well aware of the high stakes.

Caving in to U.S. and Palestinian pressure to extend the freeze could bring down the conservative Israeli governing coalition. But resuming settlement construction could spell disaster for the fledgling peace talks.

"Many options are being discussed. It's not that simple," said Foreign Ministry spokesman Yigal Palmor.

Palestinian officials said Monday that President Mahmoud Abbas had sent a letter to the U.S threatening to withdraw from the negotiations, which are set to begin next week in Washington, if the settlement freeze ends.

"If Israel resumes settlement activities in the Palestinian territories, including east Jerusalem, we cannot continue negotiations," Palestinian negotiator Saeb Erekat said, quoting from the letter. He said the document also was sent to other members of the quartet of Mideast mediators — the EU, UN and Russia.

Israel and the Palestinians appear to be jostling for position before the formal launch of negotiations on Sept. 2 at the White House. The Palestinians are taking a tough line toward settlements, while Netanyahu this week laid down key security demands.

The roughly 120 Jewish settlements that dot the West Bank have long been a sore point in Mideast peacemaking. Israel began settling the territory soon after capturing it along with Gaza and east Jerusalem in the 1967 war.

The Palestinians say the settlements, now home to roughly 300,000 Israelis interspersed among some 2.4 million Palestinians, are gobbling up land they claim for a future state. The international community considers them illegal, and U.S. President Barack Obama has been an outspoken critic.

Under intense U.S. pressure, Netanyahu imposed the slowdown last November to draw the Palestinians to the negotiating table. The move barred approval of new housing construction, though hundreds of homes already being built were allowed to be completed.

Netanyahu quietly imposed a similar slowdown in East Jerusalem early this year after a run-in with the U.S. over Israeli policies in the area.

Israel considers East Jerusalem to be an indivisible part of its capital and has annexed the area, but the international community does not recognize the annexation and considers the ring of Jewish neighbourhoods built there to be illegal settlements. The Palestinians seek East Jerusalem as their capital.

Netanyahu, a longtime ally of the settlement movement, has said the freeze is a one-time gesture. But he has not spoken publicly on the matter since the U.S. announced the upcoming resumption of peace talks Aug. 20.
