Six Al Jazeera English journalists, who were briefly detained in Egypt, have been released, however; their camera equipment remains confiscated by the military.

The move comes a day after Al Jazeera was told to shut down its operations in the country and saw its signal to some parts of the Middle East cut.

Following the arrest of the journalists a spokesman of the channel said Al Jazeera will not be deterred; "If anything, our resolve to get the story has increased."

On Sunday, Al Jazeera expressed its "utter disappointment" with the blockage of its signal on Nilesat.

International press institutes have come out strongly against Egyptian authorities' suppression of the media, following the withdrawal of Al Jazeera's license in Egypt.

The Committee to Protect Journalists (CPJ) condemned the information ministry's move to shutdown Al Jazeera’s bureau in the country.

The CPJ described the move as an attempt to "disrupt media coverage by Al Jazeera and calls on them to reverse the decision immediately".

Nilesat, the satellite transmission company owned by Egyptian radio and television stopped the transmission of Al Jazeera's primary channel and others.

Reporters without borders added to the condemnation of Egyptian authorities attempt to quell the media.

"By banning Al Jazeera, the government is trying to limit the circulation of TV footage of the six-day-old wave of protests," Reporters Without Borders secretary-general Jean-François Julliard said.

Protest organisers are calling for a "march of one million" people in Cairo, the Egyptian capital, on Tuesday in an attempt to overthrow Mubarak's rule.

They are also calling for a rolling general strike until the leader, who has been in power for more than 30 years, steps down.

Several hundred demonstrators remained camped out in Tahrir Square in central Cairo overnight, defying a curfew that has been extended by the army.
