President Hosni Mubarak urged Israel's prime minister Tuesday to do what he can to save the Mideast peace process, as U.S. mediators pressed the case for peace in both Cairo and Jerusalem.

Mubarak held separate discussions with Israeli Prime Minister Benjamin Netanyahu and U.S. envoy Martin Indyk at his al-Salam Palace to try to encourage success at an American-mediated meeting in London.U.S. Secretary of State Madeleine Albright is to meet separately with Netanyahu and Palestinian leader Yasser Arafat in London on Monday.

Henry Siegman, an American Middle East expert, also met with Mubarak and quoted the Egyptian leader as saying he urged Netanyahu to do "everything he can to make that meeting a success."

Neither Mubarak nor Netanyahu spoke to reporters after the meeting, but Mubarak's office said he had urged a "precise enacting" of all the agreements between the Palestinians and Israelis as the only way to revive peace talks.

Progress in the talks came to a halt in March 1997 after Israel announced plans to build a Jewish neighborhood in an area of Jerusalem claimed by Palestinians.

Indyk, a former U.S. ambassdor to Israel, and U.S. special Mideast envoy Dennis Ross are both in the region to encourage the reopening of peace talks.

After his talk Tuesday with Mubarak, Indyk declined to say if the U.S. effort was making gains. But he said the United States "is concerned about the consequences if we do not now achieve that breakthrough to put the process back on track."
