BREAKING NEWS UPDATE:
Egypt's top military commander says the army is now in full control of the country and President Mohammed Morsi has been replaced by the chief justice of the constitutional court as the interim head of state.
He made the announcements in a Wednesday night speech -- the latest twist in an all-out power struggle inside Egypt that Morsi's national security adviser is describing as a military coup.
Gen. Abdel-Fattah el-Sissi said the country's constitution has been temporarily suspended and Morsi has failed to meet the demands of Egypt's people.
Fireworks and cheers erupted from the millions gathered in Tahrir Square after the announcement was made.
Top military officials and opposition leaders met Wednesday and agreed on a political roadmap for the country's future, el-Sissi said. A new presidential cabinet will be formed as well as a national reconciliation committee, which will include youth movements that have been behind anti-Morsi demonstrations.
Morsi's response was not immediately known, but an aide says he has been moved to an undisclosed location.
