The resignation of Egyptian President Hosni Mubarak is sparking celebration among Egyptians worldwide. Hundreds of thousands chanted and cheered in Cairo's main square following Friday's announcement.
During a speech from the White House on Friday afternoon, President Barack Obama said it's "a beginning" for Egypt, with "difficult days ahead." But he expressed confidence in a peaceful transition. "Egyptians have made it clear that nothing less than genuine democracy will carry the day," he said.
Egypt is a longtime ally of the United States, and Obama said the nation "will continue to be a friend and partner."
Mubarak's sudden resignation comes after 18 days of huge demonstrations calling for him to leave. In a national address on Thursday, he insisted he would stay in office until September elections. But his vice president announced on Friday that Mubarak had decided to resign.
