CAIRO — Tens of thousands of Egyptian protesters are gathering in Cairo's Tahrir Square, rejecting President Hosni Mubarak's new cabinet appointments and vowing to draw 1 million marchers until the U.S.-allied authoritarian president gets the message: he must go.

A subdued Egyptian police force was back on the streets Monday morning, mostly doing crowd control and traffic direction around streets leading to the main downtown square where protestors have gathered nightly for the past week in hopes of toppling the Mubarak regime.

However, as the curfew hour neared, tensions were heating up and many protesters feared another spasm of violence between police and the crowds. This time, however, the Egyptian military also is present, and low-flying helicopters hovered over the site all day.
