Some 100,000 protesters have gathered in Cairo's downtown Tahrir Square Tuesday morning for a march to Presidential Palace in Cairo amid the mass protests demanding an end of the 30-year-rule of President Hosni Mubarak, Xinhua reporters said.
The opposition has called for a one-million-people march on Tuesday after a week of unrest in the country.
Many mini-buses carrying protestors were moving from Helwan governorate to downtown Cairo at midday Tuesday to join the protestors.
"We don't want any changes but oust the whole regime, we will never be satisfied with changing ministers," said Ahmed Abdel Karim, a 38 year-old taxi diver told Xinhua.
It is only acceptable that Vice President Omar Suleiman lead for an interim government before establishing an national unity government from all the political parties, Karim added.
"We have blankets, food and water and we will sleep in the square till the morning, we won't retreat until the change occur," he said.
Despite protesters' call for an indefinite strike and one- million-march to the presidential palace, some Egyptian intellectuals including artists and engineers are passing out leaflets, urging people to stay away from "violence" and "Chaos".
"The continuation of chaos will only deepen people's suffering and provide chances for looting and other crimes," one of the leaflets read.
The military has set up roadblocks along the way leading up to the presidential palace and checked people who are entering the Tahrir Square for weapons. Public transportation and train services connecting Cairo and other cities are suspended.
The army has said in a statement that they won't use violence against citizens, and that their only mission is to keep the security and fight looters and those who break the law.
