US secretary of state Hillary Clinton is touring Cairo's Tahrir Square, the epicentre of the popular uprising that toppled Egypt's longtime autocratic leader last month.
Mrs Clinton made an unscheduled stop to the site today during a two-day visit to Egypt aimed at encouraging the Egyptian people and their transitional leaders to hold true to the ideals of democratic reforms that propelled the revolution.
Mrs Clinton is the highest-ranking US official to visit Egypt since former president Hosni Mubarak was ousted last month and she has pledged America's support for the transition.
She will meet Egypt's army chief and prime minister before heading later today to Tunisia, where she will be bringing the same message.
The success of Tunisia's anti-government protests in January fueled similar revolts across the Arab world.
