Egypt says Israel's regret is not enough

"The Israeli statement was positive on the surface, but it was not in keeping with the magnitude of the incident and the state of Egyptian anger toward Israeli actions," the official MENA news agency quoted a cabinet statement as saying on Sunday.
MENA said the cabinet insisted on a timetable for an Israeli offer of a joint investigation into the deaths on Thursday as Israeli troops pursued fighters who carried out attacks earlier in the Negev that killed eight.
"Egypt affirms its solicitude for maintaining peace with Israel, but Israel must also assume responsibility for protecting this peace," it said.
The reaction came as thousand of Egyptians protested late on Saturday outside the Israeli embassy in Cairo, housed in the top floor of a high-rise building.
Israeli flag removed
An Egyptian protester on Sunday clambered up to the embassy, took down its flag and replaced it with an Egyptian one as more than 1,000 people protested over the border deaths of their policemen.
