JERUSALEM, Nov 13 (Reuters/Allyn Fisher-Ilan) - Prime Minister Benjamin Netanyahu showed senior ministers a U.S. plan for resuming peace talks with Palestinians, including a 90-day settlement freeze, a diplomatic source told reporters on Saturday.

The also plan includes a pledge not to seek any extension to the settlement freeze after the 90-day period, a vow to veto any attempts at the United Nations to force a unilateral peace deal and an agreement on supplying Israel with more war planes.

Israeli-Palestinian peace talks, renewed under Washington's sponsorship on Sept. 2, broke down a few weeks later when Israel balked at renewing a settlement moratorium.

Netanyahu met his top Forum of Seven ministers a day after returning from a week-long U.S. tour that included talks on Thursday with U.S. Secretary of State Hillary Clinton at which she unveiled the plan he showed his cabinet, the source said.

Netanyahu hopes he may win approval for the plan from his pro-settler cabinet later this week, political sources said.

Among the pledges offered to Israel by Washington, was a guarantee to veto any resolutions brought to the United Nations Security Council that seek to impose a political settlement on Israel, the source said, speaking on condition of anonymity.

Palestinian President Mahmoud Abbas had no immediate comment. Officials speaking on condition of anonymity said the Palestinian leader was likely to wait to see whether Israel approved the ideas before issuing any comment.

AN ADDITIONAL FREEZE

Under the plan Israel would declare an additional suspension of construction in the West Bank, land it captured from Jordan in a 1967 war, for 90 days. Building begun since a moratorium ended in September, would be halted, the source said.

The proposed construction freeze would not include East Jerusalem, an area Israel has annexed as part of its capital in a move never recognised internationally and which Palestinians want as capital of any future state.

Washington would also undertake to veto resolutions deemed anti-Israel in the U.N. Security Council and other international organisations, the source said, a pledge that could make Israel less vulnerable to threats made by some Palestinians to declare statehood unilaterally in the event that peace talks fail.

The Obama Administration would also ask Congress to approve the supply of $3 billion worth of warplanes to Israel to maintain its qualitative edge in the region, the source said.

The United States would further sign a more comprehensive deal to enhance its substantial security aid to Israel as part of any agreement concluded with the Palestinians.

Israeli officials said Netanyahu, who faces a tough political sell within his own coalition on the settlement issue, had pushed Clinton for the broad understandings.

The chances of reaching a peace agreement will be improved significantly by achieving comprehensive security understandings between Israel and the United States, Netanyahu said in New York before his talks with Clinton began.
