There has been fresh violence between Israeli forces and Palestinian militants.
Today, militants fired at least 20 rockets from Gaza into Israel and the Israeli air force carried out four more raids, attacking targets in the Palestinian territory.
Since Thursday, rocket attacks on Israel have killed one man and injured dozens of others, while Israeli air strikes over the past few days have killed at least 15 people in the Gaza Strip, and injured dozens more.
Efforts are continuing between Egypt and Israel to defuse a diplomatic crisis over the killing of five Egyptian security personnel during an Israeli operation against cross-border raiders.
Crowds of Egyptians have protested angrily at the Israeli embassy in Cairo.
One demonstrator scaled several floors of the high-rise embassy building overnight to tear down the Israeli flag and replace it with an Egyptian one.
Several hundred protesters remained in front of the Israeli embassy near the Nile waterfront today, watched over by hundreds of troops and police. Some said they would stay until Israel's ambassador is ejected from Egypt.
A protest of any size near the Israeli embassy would have been quickly smothered by state security in the era of former President Hosni Mubarak.
The Cairo-based Arab League condemned ‘the Israeli attack on the Egyptian forces’ in a statement and said Israel bore ‘full responsibility for this crime’.
However, there were signs that Egypt and Israel were both trying to ease the gravest crisis in their relations since former ruler Mubarak's overthrow in February.
Yesterday, Egypt said it would recall its ambassador from Israel after the killings, but it was unclear if the withdrawal would go ahead. The Foreign Ministry summoned the Israeli charge d'affaires to protest and demand a joint investigation.
Israeli Defence Minister Ehud Barak said Israel regretted the deaths and told the army to conduct the investigation with Egypt, which responded with cautious approval.
A delegation led by an unidentified high-ranking Israeli envoy arrived in Cairo on a private plane from Tel Aviv today to a low-key reception.
