There's concern that mass protests planned for tomorrow in Egypt could plunge the country into a dangerous round of civil unrest.
Clashes in the past week have left at least seven people dead, including an American, and hundreds injured.
A youth group leading a campaign against President Mohammed Morsi says it has collected the signatures of 22 million Egyptians who want to remove the Islamist leader.
The U.S. government is warning Americans to steer clear of Egypt if possible after a 21-year-old college student, Andrew Pochter of Chevy Chase, Md., was killed yesterday while photographing battles between supporters and foes of Morsi.
President Barack Obama says, "We're all looking at the situation there with concern."
The State Department has urged Americans to forego all but essential travel to Egypt and moved to reduce the official U.S. presence in the country. Officials said they would allow some nonessential staff and the families of personnel at the embassy to leave the country until conditions improve.
