"Dozens of members from Youth for Freedom and Justice, the April 6 Youth movement, and Kefaya, The Egyptian Movement for Change, organized a march to the home of the Israeli Ambassador in Maadi to protest the killing of 16 security officers near the Egyptian-Israeli border on Sunday afternoon.
The protesters called for the expulsion of the Ambassador and to punish those who perpetrated or colluded in the attack.
Officials from Egypt and Israel said the attackers belonged to extremist Islamist groups in Sinai, but Islamist politicians and observers in Egypt said they suspect that Israel was behind the incident.
The protesters chanted slogans against Israel and raised black banners that read "in mourning."
Wessam Aly, one of the participants in the protest, said he held the Supreme Council of the Armed Forces accountable for the attack and called for revealing the identities of the assailants.
Israel had closed its embassy in Cairo after protesters stormed it in September after six Egyptian border guards were killed in August by Israeli forces, who said they were targeting terrorist elements."
