We begin in Egypt, where riots have brought chaos and tension in the north African nation for a week now. Despite a series of concessions made by the president, Egyptian Protesters began to march to Presidential Palace in Cairo amid the mass protests demanding an end of the 30-year-rule of President Hosni Mubarak.

Some 100,000 people have so far gathered in Tahrir Square on Tuesday morning, as the opposition called for a one-million-people march on Tuesday after a week of unrest in the country.

Crowds are now gathering in central Cairo for a protest organizers hope will swell to a million people as they continue their push to end the 30-year-rule of President Hosni Mubarak. Yuan Yani has more details.

Protestors are converging in Tahrir Square to prepare for what they call a "million-man march," to the presidential palace.

Army tanks and troops are surrounding the square as helicopters hover above, but the army hasn't stopped people from joining the demonstration.

The protesters are calling for President Hosni Mubarak, who has been ruling since 1981, to step down.

Mubarak has defied the demands. But he replaced the cabinet and dismissed the detested interior minister for the first time. However, other key ministers are retaining their posts.

In another move, Vice President Omar Suleiman announced Monday afternoon the Egyptian president appointed him to hold immediate talks with the opposition.

But the crowds sneered at the moves, saying they don't want old faces in the new government because they are not chosen by the Egyptian people. They're demanding a new government with no links to President Hosni Mubarak.

The protesters were bolstered by Egypt's military, which has called their demands "legitimate."

In a statement aired Monday on state TV, the armed forces urged citizens not to loot, but assured them soldiers would not open fire as long as they remain peaceful.
