Egyptian President Hosni Mubarak stepped down on Friday after 18 days of mass protests against his rule.
Here is some reaction from around the world:
US President Barack Obama:
-- "The President was informed of President Mubarak's decision to step down during a meeting in the Oval Office. He then watched TV coverage of the scene in Cairo for several minutes in the outer Oval (office)," White House spokesman Tommy Vietor said.
-- Obama is to deliver a statement on Egypt at 1830 GMT.
EU foreign policy chief Catherine Ashton
-- "The EU respects President Mubarak's decision today. By standing down, he has listened to the voices of the Egyptian people and has opened the way to faster and deeper reforms," Ashton said.
"It is important now that the dialogue is accelerated leading to a broad-based government which will respect the aspirations of, and deliver stability for, the Egyptian people."
"The future of Egypt rightly remains in the hands of the Egyptian people. The EU stands ready to help in any way it can."
