The Egyptian judges’ body has called on judges and other judiciary officials to strike in protest at a decree issued by President Mohammed Mursi which shields his decisions from judicial review.

At a meeting in Cairo, the Judges Club called on Mr Mursi to retract the decree and to reinstate Abdel Maguid Mahmoud, the Hosni Mubarak-era prosecutor general who was sacked as part of the decision unveiled on Thursday.

Earlier, the judges' club in Alexandria said work would be suspended in all courts and prosecution offices until the decree was reversed.

The Egyptian democracy advocate and opposition leader ElBaradei has said there will be no dialogue with the president until these new powers are rescinded.

He has also called for peaceful protests.

Last night, angry youths hurled rocks at security forces and burned a police truck protesting over Egyptian President's decision to grab sweeping new powers.

Police fired tear gas near Tahrir Square, heart of the 2011 uprising that toppled Hosni Mubarak at the height of the Arab Spring.

There were also violent protests in Alexandria, Port Said and Suez.

In Alexandria, north of Cairo, protesters ransacked an office of the Brotherhood's political party, burning books and chairs in the street.

Supporters of President Mursi and opponents clashed elsewhere in the city, leaving 12 injured.

A party building was attacked by stone-throwing protesters in Port Said, and demonstrators in Suez threw petrol bombs that burned banners outside the party building.

Thousands demanded that Mr Mursi should quit and accused him of launching a "coup".

President Mursi last Thursday issued a decree that puts his decisions beyond any legal challenge until a new parliament is elected.

Opponents immediately accused him of turning into a new Mubarak and hijacking the Egyptian revolution.

The US, the EU and the United Nations expressed concern at Mr Mursi's move.

President Mursi's rivals condemned him as an autocratic pharaoh who wanted to impose his Islamist vision on Egypt.

The president's aides said the decree was intended to speed up a protracted transition to democracy that has been hindered by legal obstacles

"I am for all Egyptians," Mr Mursi said on a stage outside the presidential palace, adding that he was working for social and economic stability and remained committed to the revolution.
