Egyptians sit on a wall as they attend a protest against the deaths of Egyptian security forces killed in a shootout between Israeli soldiers and Palestinian militants on Thursday in the Sinai, in front of the Israeli embassy in Cairo, Egypt, Saturday, Aug. 20, 2011. Egypt said Saturday it would recall its ambassador from Israel to protest the deaths, sharply escalating tensions between the neighboring countries, whose 1979 peace treaty is being tested by the fall of Egypt's longtime autocratic leader, Hosni Mubarak.
