Cairo (Agencies): Egypt's new military rulers claimed that they were committed to civilian rule and democracy after Hosni Mubarak's overthrow and said they would respect all treaties, a move to reassure Israel and Washington.

Some pro-democracy campaigners in Cairo's Tahrir (Liberation) Square, the epicentre of an earthquake of popular protest that unseated Mubarak, have promised to stay there until the Higher Military Council accepts their agenda for democratic change.

If the military fails to meet "people's demands", protest organisers threatened they would stage more demonstrations.

Throughout the Middle East, autocratic rulers were calculating their chances of endurance after Mubarak was forced from power in a dramatic 18-day uprising that changed the course of Egypt's history, unsettling the United States and its allies.

"The Arab Republic of Egypt is committed to all regional and international obligations and treaties," a senior army officer stated, delineating the armed forces' extensive strategies at home and abroad.

The message was evidently designed to try and pacify concerns in Israel which has a 1979 peace treaty with Egypt, the first Arab nation to make peace with the Jewish state. Israeli Finance Minister Yuval Steinitz welcomed the statement.

In another move to reinstate order, the army said it would "guarantee the peaceful transition of power in the framework of a free, democratic system which allows an elected, civilian power to govern the country to build a democratic, free state".

After the army statement, Egypt's Muslim Brotherhood, viewed suspiciously by the United States, said it was not seeking power and praised the army's plans to transfer power to civilians.

Crowds celebrated in Tahrir Square while protest organisers urged the army to meet demands including the dissolution of parliament and the lifting of a 30-year-old state of emergency used by Mubarak to crush opposition and rebel.
