There is no single emotion that defines a revolution. Across Cairo, 30 years of autocracy are pouring out in streams of tears and screams of joy.

But the hope, fear and uncertainty coursing through the Egyptian uprising is shaking Israel.

Peace with Egypt under President Hosni Mubarak has been, according to one defence official, "Israel's second biggest strategic asset after the United States".

Benjamin Netanyahu has appealed to the anti-government protesters to maintain Egypt’s peace treaty with Israel if they succeed in overthrowing the government of President Hosni Mubarak.

The Israeli Prime Minister expressed his support for democratic reform in Egypt as demonstrations in the Arab country continued for an eighth consecutive day.

Mr Netanyahu offered cautious backing to the protesters with a statement in which he said he encouraged “the advancement of free and democratic values in the Middle East”.

The King of Jordan has dismissed his government and named a new Prime Minister, as anti-government protests continue around the Arab world.

King Abdullah II has asked his new Prime Minister, Marouf Al Bakhit, to move the country along the path to democracy.

He has replaced Samir Rifai in the role, but it does not necessarily represent a break with the past – Mr Al Bakhit was Prime Minister from 2005 to 2007.

A leading figure in world Jewry has labelled the Egyptian opposition leader Mohammed ElBaradei “a stooge” of the Iranian regime.

Malcolm Honlein, the executive vice-president of the Conference of Presidents of Major American Jewish Organisations, accused Mr ElBaradei of fronting for Iran and “distorting reports” during his 12 years as director of the International Atomic Energy Agency.

The Israeli Foreign Ministry has issued a travel warning for its citizens in Egypt as mass anti-government protests entered a third day.

Yossi Levy, a Foreign Ministry spokesman, said the department has not instated a travel ban but that it is advising people to “pay close attention to developments”.

He said: “[People should] be very cautious and obey the instructions of security officers on the ground and keep their distance from demonstrations and the centre of town,”

It is tempting to lump the unrest sweeping the Arab world this week into one tidal wave, but the scenario in each country is unique.

Speculation is growing as to whether President Hosni Mubarak will be able to hold on to power in Egypt.

It has been rumoured that the Egyptian leader’s family, including his wife and son, had fled for London, although CBS News reported that an embassy official had denied this.

Violent demonstrations broke out in Cairo and other places across the country yesterday. Security forces used tear gas and water cannons to try and break up the crowds.
