Dozens of Egyptians protested  on Monday evening into the early hours of Tuesday morning in front of the residence of the Israeli ambassador in the Maadi district of Cairo.
Witnesses living in the area told UPI that dozens of Egyptians demanded the expulsion of envoy Yaakov Amitai following a deadly militant attack in Sinai which left 16 Egyptian soldiers dead.
Demonstrators chanted "Oh Zionist, oh cowards, Egyptian blood is not cheap," "Retribution, retribution, they shot our sisters with bullets," and "Get out, ambassador of swine."
Security forces surrounded the house of the ambassador to prevent demonstrators from storming it, fearing a repeat of events last year when the Israeli embassy was raided twice.
Israel returned the bodies of six gunmen, involved in the killing of the Egyptian troops during a raid on both sides of the border, to its Arab neighbor, Israeli military sources told AFP on Tuesday.
The six were sent back overnight Monday, they said.
The Israeli army said in a statement that the Karm Abu Salem border crossing between Israel, Egypt and Gaza, which the attackers breached in Sunday's raid, was reopened on Tuesday morning.
In Sunday's attack, 35 gunmen in Bedouin clothing opened fire on Egyptian troops before crossing into the Jewish state in an armored vehicle, Egyptian officials said.
Israel said five gunmen were killed on its side, adding that the armored vehicle was destroyed by helicopter fire.
Israeli media said that the remains of a sixth man was recovered from an explosive-laden pickup truck which blew up as it tried to negotiate barriers at the border crossing.
Brotherhood blames Mossad
Egypt's Muslim Brotherhood, the movement of President Mohammed Mursi, said on its website that the attack "can be attributed to Mossad."
The statement said Mossad, the Israeli intelligence agency, was trying to abort the Egyptian uprising that toppled president Hosni Mubarak last year and that it was "imperative to review clauses" of the agreement between Egypt and Israel.
The group said on its website on Monday: "This crime can be attributed to the Mossad, which has been seeking to abort the revolution since its inception and the proof of this is that it gave instructions to its Zionist citizens in Sinai to depart immediately a few days ago."
Israel on Monday dismissed the charge.
"Even the person who says this when he looks at himself in the mirror does not believe the nonsense he is uttering," Israeli Foreign Ministry spokesman Yigal Palmor said.
The Brotherhood also called for a review of the 1979 peace treaty with Israel,  which prohibits Egypt from deploying a large military presence in the Sinai.
"(It) also draws our attention to the fact that our forces in Sinai are not enough to protect it and our borders, which makes it imperative to review clauses in the signed agreement between us and the Zionist entity," the group said.
Egypt also closed until further notice its Rafah crossing with the Gaza Strip, the only crossing to and from the territory not controlled by Israel.
