U.S. Secretary of State Hillary Clinton has toured Cairo's Tahrir Square, the epicenter of the popular uprising that toppled Egypt's longtime autocratic leader last month.
Clinton is on a two-day visit to Egypt to press the country's new military rulers to follow through on pledges of democratic reform.
She is the highest-ranking U.S. official to visit Egypt since President Hosni Mubarak was forced to resign in mid-February.
Clinton was traveling later in the day to Tunisia.
The success of Tunisia's antigovernment protests in December inspired similar revolts in many countries in the Arab world.
