2200 GMT: Tonight's statement from protesters calling for the fall of the Egyptian Government and for a continued sit-in:
In Tunisia, there continue to be dramatic developments. Amidst chatter that the interim Government would be replaced by a "council of wise men" to give the country a semblance of authority before March elections, the head of the Army, Rachid Ammar, suddenly appeared before protesters outside the Prime Minister's office (see Monday's updates).
Ammar's message was a request to the thousands of demonstrators and a warning to the politicians. He asked those assembled to finish their protest and allow a bit of space for discussions. And his declaration that the Army supported the people's revolution and would uphold the Constitution sent out the message to those inside the Government buildings: get this sorted now.

1920 GMT: In Egypt, a man tried to commit suicide by cutting his wrists as about 20 people gathered in front of the Supreme Court to commend the police’s work and criticize protests planned for Tuesday.
Civil servants have received a written warning not to participate in the demonstrations for a "day of revolution against torture, poverty, corruption and unemployment". Those who defy the instruction could lose their jobs.
