IN A SCENE REMINISCENT OF THE ARAB SPRING, HUNDREDS OF THOUSANDS OF PROTESTORS JAMMED CAIRO'S TAHRIR SQUARE. MANY CALLING FOR THE OUSTER OF EGYPT'S ISLAMIST PRESIDENT Mohammed Morsi.

(NATS IN ARABIC)

THIS MAN SAYS THE PROTESTORS WILL NOT LEAVE UNTIL MORSI LEAVES.

AT THE SAME TIME, THE MILITARY IS MAKING ITS OWN PLANS. THE ARMY HAS GIVEN A WEDNESDAY DEADLINE FOR MORSI TO RESOLVE DIFFERENCES WITH HIS OPPONENTS. If not, THE MILITARY OUTLINE CALLS FOR SUSPENDING THE CONSTITUTION, DISSOLVING THE LEGISLATURE AND SETTING UP AN INTERIM ADMINISTRATION.

MORSI WAS ELECTED JUST A YEAR AGO FOLLOWING THE OUSTER OF HOSNI MUBARAK.

FOR ITS PART, THE OBAMA ADMINISTRATION IS ABANDONING IT'S HANDS-OFF APPROACH. THE PRESIDENT CALLED MORSI BEFORE LEAVING AFRICA.

OFFICIALS SAY OBAMA DELIVERED A THREE-PRONGED MESSAGE--TELLING MORSI TO ADDRESS OPPOSITION GRIEVANCES, PROTESTORS TO REMAIN PEACEFUL--AND WARNING THE ARMY THE EGYPT WOULD LOSE IT'S MASSIVE MILITARY AID IF THERE'S A COUP.

IN ADDITION TO PROTESTS, MORSI IS DEALING WITH THE DEFECTIONS OF A NUMBER OF HIGH-LEVEL GOVERNMENT OFFICIALS.

TUESDAY ALSO SAW A COURT INVALIDATE MORSI'S WIDELY-DISPUTED APPOINTMENT OF THE COUNTRY'S ATTORNEY GENERAL.

BUT MORSI'S BACKERS HAVEN'T BEEN QUIET. ONE GROUP OF SUPPORTERS SAID IT WOULD TAKE BLOODSHED TO REMOVE MORSI FROM OFFICE.
