Hundreds of thousands of Egyptians gathered Tuesday in Cairo's Tahrir Square.
Initial reaction is highly unfavorable to President Hosni Mubarak's announcement that he intends to stay in office through elections in September.
NBC News' Richard Engel reported from Cairo that the hundreds of thousands of protesters gathered in Tahrir Square were likely to find the speech "unsatisfactory" because they want Mubarak out immediately.
As protesters watched Mubarak on a giant TV screen, they chanted, "Leave! Leave! Leave!" Organizers remained defiant and vowed to stage another "March of the Millions" on Friday after prayers, NBC's Ron Allen reported.
Allen said protesters seemed "stunned" by Mubarak's refusal to leave. Some said they intended to stay in the square until Mubarak left the country.
"The bottom line is this has always been a fairly loosely organized opposition ... so I think people are trying to figure out what to do now," Allen reported. "A lot of people in this country are not happy."
There was no immediate reaction from the White House, where President Barack Obama and his entire national security team watched the speech in the Situation Room, NBC's Savannah Guthrie reported from Washington. NBC News previously reported that Obama, through an envoy, tried to persuade Mubarak to leave.
A spokesman for the Muslim Brotherhood, Egypt's largest opposition movement, told The Wall Street Journal that "no one is satisfied" and that protests would continue.
