Authorities in Egypt are concerned that riots may break out in Tahrir Square after the Friday prayers. 

A group known as the "Egyptian Revolutionary Coalition" published a call Thursday to Egyptians to rally en masse at Tahrir Square in order "to express anger at the continued deterioration of the economic situation and the social exploitation, as well as the limitation of freedoms and the threat to a free press."

Sources in the Egyptian Revolutionary Coalition told reporters that the group rejects the present transitional government's policies, which are meant to sow discord in the opposition by making empty promises to carry out the revolution's demands. They blamed the government of Field Marshal Muhammad Tantawi of trying to buy time at the expense of stability in Egypt.

Egypt, they said, needs "to move quickly possible past the transitional phase, which has become a phase of revenge against the revolution and revolutionaries."

Al Sharq al Awsat reported Thursday that the atmosphere of political stability in Egypt is fast eroding. Reuters said that six possible candidates for president demanded that the elections be sped up and held in April. 

Today (Thursday), October 6, is the 30th anniversary of the murder of Anwar Sadat, and the ascent of Hosni Mubarak to power. The assassination was carried out during a military parade that marked the anniversary of the crossing of the Suez Canal in the Yom Kippur War, on October 6, 1973.
