In a statement on events unfolding in Egypt, the US President Barack Obama urged the Egyptian army to ensure power was handed over "to move quickly and responsibly to return full authority back to a democratically elected civilian government as soon as possible through an inclusive and transparent process."

"As I have said since the Egyptian Revolution, the United States supports a set of core principles, including opposition to violence, protection of universal human rights, and reform that meets the legitimate aspirations of the people. The United States does not support particular individuals or political parties, but we are committed to the democratic process and respect for the rule of law. Since the current unrest in Egypt began, we have called on all parties to work together to address the legitimate grievances of the Egyptian people, in accordance with the democratic process, and without recourse to violence or the use of force."
