Israel's chief negotiator in talks with the Palestinians has rebuked her fellow ministers for criticizing U.S. Secretary of State John Kerry's peace efforts.

Tzipi Livni told Israel Radio on Wednesday that some members of the governing coalition are opposed to any kind of peace agreement, and that the recent verbal attacks on Kerry are "shocking."

Livni's comments point to a widening divide in the center-right coalition, which has some members backing a peace deal while others seek to prevent one based on Kerry's outlines.

Kerry is soon expected to present a framework that would define the outlines of a final deal.

Minister Naftali Bennett, who supports Jewish settlements, threatened this week to bolt the coalition if his party deems Kerry's proposal unacceptable. Other ministers have also criticized Kerry's approach.
