Palestinian President Mahmoud Abbas told his Israeli counterpart Wednesday he would not let opponents of his West Bank-based administration "kill" the peace process, DPA reported.
He was referring to unrevealed sources who leaked classified documents on sensitive negotiations between the Palestinian Authority and Israel to the al-Jazeera satellite broadcaster.
Abbas made the remark in a telephone call to Israeli President Shimon Peres, expressing condolences for the loss of Peres' wife, who died last week in Tel Aviv, aged 87.
"I very much appreciate your strong stance against the provocative attempts to delegitimize the Palestinian Authority and the peace process," Peres told Abbas, according to a spokesman in his Jerusalem office.
Abbas replied: "We must stand solidly against these attempts, you and us together. We will not let the peace process be killed."
