CAIRO(Reuters) - Jordan‘s King Hussein joined Egyptian President Hosni Mubarak and Palestinian President Yasser Arafat in Cairo on Sunday for a mini-summit on how to break the deadlock in Middle East peace efforts. The talks, which began at 0935 GMT, were expected to focus on an Israeli plan to expand the boundaries of Jerusalem, as well as what Egyptian Foreign Minister Amr Moussa called the „deteriorating conditions in the Palestinian territories“. All three leaders have criticised Israel‘s plan to extend the borders of Jerusalem into Israel proper and link it to Jewish settlements in the occupied West Bank. Mubarak, Hussein and Arafat, whose last meeting was in September, blame right-wing Israeli Prime Minister Benjamin Netanyahu for the breakdown in Palestinian-Israeli peace talks. Earlier on Sunday, Ahmed Abdul-Rahman, secretary-general of the Palestinian Authority‘s cabinet, urged Arabs to reconsider their ties with Israel. Moussa was quoted by Egyptian newspapers as saying that Mubarak, Hussein and Arafat would talk about a U.S. initiative aimed at restarting the negotiations. Under the U.S. plan — accepted by the Palestinians but rejected by Israel — Israel would withdraw from another 13 percent of the West Bank in return for Palestinian action against militants. Mubarak and French President Jacques Chirac met in Paris in May and proposed an international conference of states interested in Middle East peace and not at war with Israel. Egypt and Jordan are the only two Arab countries to have signed peace treaties with Israel but the stalemate in the peace talks has strained their ties with the Jewish state. Tension rose in the Gaza Strip on Thursday after Palestinian police and Israeli soldiers pointed rifles at each other during a stand-off.
