Palestinian caretaker prime minister has expressed doubt about the outcome of holding talks with Israel, accusing Tel Aviv of breaching its commitments.

The Ramallah government has agreed to start US-mediated peace negotiations with Israel on Wednesday, despite sharp opposition from Hamas and a number of Fatah leaders who argue the resumption of talks will only enable further "Israeli violations."

Speaking to al-Hurra TV channel on Sunday, de facto Premier Salam Fayyad said "massive" US intervention was required to ensure that the negotiations would succeed.

Fayyad complained that Israel is sticking to its expansionist projects in the West Bank and continues grabbing lands which are designated for the future Palestinian state, particularly in East al-Quds (Jerusalem).

Fayyad also criticized Israel for violating its agreements with the Palestinian Authority and accused Tel Aviv of disrupting the work of Palestinian security forces in the West Bank.

"According to the agreements and understandings, Israel is obligated to allow the security forces to operate in the West Bank territories and avoid raiding territories that are under the security forces’ supervision, but the Israelis are not respecting and are continuing to thwart our efforts," Fayyad said.

"Israel has not lived up to all of its obligations since the Annapolis Conference," he charged.

Regarding his earlier remarks about a decision to unilaterally declare a Palestinian state, a state will not be declared by August 2011. But "as far as government institutions are concerned, we will be prepared for the establishment of a Palestinian state."
