CAIRO (AP) — Egypt and Jordan harshly criticised Israel over its actions in Gaza at a summit on Saturday, a sign that the two Western allies that made peace with Israel decades ago are losing patience with its two-week-old war against Hamas.

Egyptian President Abdel Fattah el-Sissi, who hosted the summit, again rejected any talk of driving Gaza’s 2.3 million Palestinians into the Sinai Peninsula and warned against the “liquidation of the Palestinian cause.” Jordan’s King Abdullah II called Israel’s siege and bombardment of Gaza “a war crime.”

The speeches reflected growing anger in the region, even among those with close ties to Israel who have often worked as mediators, as the war sparked by a massive Hamas attack enters a third week with casualties mounting and no end in sight.

Egypt is especially concerned about a massive influx of Palestinians crossing into its territory, something that it fears would, among other things, severely undermine hopes for a Palestinian state. Vague remarks by some Israeli politicians and military officials suggesting people leave Gaza have alarmed Israel’s neighbours, as have Israeli orders for Palestinian civilians to evacuate to the south, toward Egypt.

In his opening remarks, el-Sissi said Egypt vehemently rejected “the forced displacement of the Palestinians and their transfer to Egyptian lands in Sinai.”

“I want to state it clearly and unequivocally to the world that the liquidation of the Palestinian cause without a just solution is beyond the realm of possibility, and in any case, it will never happen at the expense of Egypt, absolutely not,” he said.

Jordan’s king delivered the same message, expressing his “unequivocal rejection” of any displacement of Palestinians. Jordan already hosts the largest number of displaced Palestinians from previous Mideast wars.

“This is a war crime according to international law, and a red line for all of us,” he told the summit.

Palestinian President Mahmoud Abbas, who leads the Palestinian Authority, a government exercising semi-autonomous control in the occupied West Bank, called for Israel to stop “its barbaric aggression” in Gaza. He also warned against attempts to push Palestinians out of the coastal territory.

“We will not leave, we will not leave, we will not leave, and we will remain in our land,” he told the summit.

Israel says it is determined to destroy Gaza’s Hamas rulers but has said little about its endgame.
